Introduction To Vision II. The P&B Vision II series builds upon the success of the original Vision series. It is a new generation of Intelligent Protection Controllers, which now offers a greater combination of power, flexibility and ease of use. The Vision II relay is a totally integrated device intended to provide all monitoring, protection & control function normally provided on a vacuum, air circuit breaker or starter device by separate expensive components such as protection relays, meters, lamps, push buttons etc. The Vision II series will comprise of: • • • • • Motorvision II. Advanced Motorvision II. Feedervision II. Feedervision II With Trip Circuit Supervision. Advanced Feedervision II. At the core of the Vision II series is the hardware and software design. Major advances by P&B in the design of electronic circuits and the use of surface mount printed circuit board technology have produced an extremely compact unit smaller than all known similar devices available today. This, combined with a totally modular hardware and software design, gives the product the flexibility to expand and adapt to suit any protection controller application. 1.1. Common Vision II Features. DIN Standard, Compact Case. Vision II is supplied in an internationally recognised DIN size cases measuring only 144 x 96 x 129mm (196 x 96 x 129mm for the Feedervision II, Feedervision With TCS II, Advanced Feedervision II and Advanced Motorvision II). The case is supplied for flush mounting with standard option of a dustproof-hinged cover with key lock etc. The Vision II series can be installed into some of the smallest Low Voltage compartments available allowing high stacking density per tier. Graphical LCD Display. Dominating the front facia of the Vision II is a 50mm x 50mm backlit graphical liquid crystal display. Vision II is the first Protection Controller supplied at a market competitive cost to use this type of LCD display technology. The display gives a resolution of 128 x 128 pixels, this allows up to 16 lines of 21 text characters to be displayed at the same time eliminating the need for confusing abbreviations and the need to constantly select different pages of data, as is often the case with devices using limited character displays. P&B Engineering Issue 3 9/08/2007 Page 1 ADVANCED FEEDERVISION 2 TECHNICAL MANUAL The use of the graphics capability is further expanded by Vision II for instance when a motor starts the Vision II will automatically display an accurate trend of the time versus current characteristic which can be recalled later. The operator will instantly understand the curve and should be able to tell at a glance if the starting characteristic is normal as Vision II can also display a memorised characteristic from a previous start. The graphic display also allows Vision II to need only 4 function buttons as opposed to 10 or more on most similar devices. This results in a user friendly interface which is achieved by the present function of each button always being displayed which enables the 4 buttons to allow full interrogation and operation of the unit by untrained personnel. The use of this display is fundamental to P&B’s design philosophy, which is to provide powerful comprehensive products that can easily be used by operators without the need for specific training. The facility to display up to 16 lines of 21 characters allows comprehensive and fully descriptive help to be provided through a powerful learn mode, which takes the user through the display system. Terminations. Terminals are located on the rear of the rear of unit and are supplied with industry standard plugin blocks to allow easy installation and removal. The terminals are suitable for connecting up to 1.5 sq. mm crimped conductors. The current inputs to the relay are screw terminals - as opposed to the plug-in blocks that are used for the other terminals. Control Inputs. Vision II includes 24 optically isolated digital input channels, which are programmable to provide comprehensive monitoring of the control circuit status and interfacing with all necessary items of external equipment. Control Outputs Vision II includes 8 control outputs to allow sequenced control of contactors, circuit breakers and remote indication of the units status etc. Five out of the eight relays are fully programmable. Analogue Inputs. Transformer isolated inputs are included to allow Vision II to monitor 3 phase current, earth current, standby earth current, voltage, (3 phase for Feedervision II, Feedervision II With TCS and Advanced Feedervision II). Page No. 2 Issue 3 9/08/2007 P&B Engineering ADVANCED FEEDERVISION 2 TECHNICAL MANUAL Analogue Outputs. To allow Vision II to output special variables such as speed control to a variable speed drive an optically isolated 4 - 20mA output is provided as an optional extra, which can be adjusted using either the display or serial communications. Protection. By monitoring the measured inputs Vision II provides highly accurate and flexible protection. Protection functionality for the Vision II Range use existing and field proven software and hardware design from the established and proven P&B MR series of Digital Protection relays. Self Supervision. For security Vision II includes comprehensive hardware and software watchdog self supervision routines offering the user the comfort that should any problem occur which effects the operation of the unit an Alarm will be raised and detailed error codes given to assist rapid rectification. Security. To prevent un-authorised tampering with settings or un-authorised control of a circuit separate password restrictions are applied to allow operators to restrict operations allowed. RS485 Serial Communications. The Vision II series includes a RS485 serial port to allow up to 32 Vision II units to be connected together in a daisy chain or multi-drop configuration. The system can be supplied with a Slave Modbus RTU protocol which will allow the units to interface directly with all major Distributed Control and PLC systems. The relay is also available with P&B’s own protocol which will allow Vision II units to be connected to the established XXCell Data Concentrator system where larger Distributed Communication Systems or Intelligent Dual Redundancy may be required. Either protocol allows access to all measured and calculated data as well as allowing the control system to monitor status or control circuits using only the twisted pair serial communication paths. Full details of the P&B XCell Data Concentration system and protocol details are available from P&B on request. P&B Engineering Issue 3 9/08/2007 Page 3 ADVANCED FEEDERVISION 2 TECHNICAL MANUAL 2. P&B's Advanced Feedervision II The P&B's Advanced Feedervision II is a highly sophisticated microprocessor based feeder protection and control unit, designed specifically for use on low or medium voltage feeders as an integral part of any type or manufacture of distribution equipment. All of the latest features are included in the Advanced Feedervision II to allow total control, protection and monitoring of distribution feeders either by direct hard wire inputs or via the RS485 serial port. Advanced Feedervision II can be used to control air circuit breakers, vacuum circuit breakers and contactors and true RMS current sampling at 0.5msec intervals enables the unit to be used in conditions where the measured current has a high harmonic content. Advanced Feedervision II monitors current and voltage inputs to provide a comprehensive feeder protection package. This is combined with all the necessary control and monitoring functions and a high-speed communications facility. The unit is a small, easily installed package supplied at a very competitive cost, which makes the Advanced Feedervision II the most attractive Feeder Protection and Control device available today. All hard-wired control inputs are connected to the device via optically isolated inputs to enable all opening, closing and tripping commands to be carried out by the unit. Status of all individual hard-wired contacts is also provided both locally via the liquid crystal display and remotely via the RS485 communications port. All Setting parameters are programmed independently for each unit via the integral keypad and liquid crystal display on the front plate or via the RS485 communications port and the IBM PC based software package available for the Vision II series of products. During operational conditions the LCD also gives access to accurate load, statistical and fault data such as; Volts, Phase Amps, Time to Trip, In Service Hours, Number of operations. Large Light Emitting Diodes mounted on the front plate give visual indication of the breaker status i.e. OPEN/CLOSED/TRIPPED and ALARM/TRIP/HEALTHY conditions etc. Flexible high speed control via PLC or DCS systems is obtained through the Advanced Feedervision II’s RS485 communications port, allowing computer access to full control and monitoring of feeder data, including: measured data, statistical data and control input status.

Advanced Feedervision II Analogue Inputs. 7.1. Power Supply Live. The Advanced Feedervision II requires 110V DC, 220V DC, 240V AC or 110V AC to supply the unit and provides the selected AC voltage to all external inputs. The voltage required should be specified when ordered. 7.2. Voltage Reference. The Advanced Feedervision II monitors three phase voltage which can be directly connected for voltages up to 415V. Through the use of Voltage Transformers the unit can measure line voltage upto 33kV. 7.3. Current Sensor Inputs. The Advanced Feedervision II allows connection of standard 1 amp or 5 amp secondary current transformers. The current transformers are connected via terminal block 19 and terminal block 20 is then linked to connector block 18 via a ribbon cable, supplied with the unit. 7.3.1. Overcurrent Poles. The Advanced Feedervision II allows the connection of either of the following: Two Phase Current and Two Earth Fault Phases Three Phases Current and One Earth Fault Phase. In the case of Two Earth Fault Phases the currents in Phase I1 and I2 are measured from the RED and YELLOW phase. I3 is calculated from the readings of I1 and I2. (I3 is the NEGATIVE VECTOR SUM of I1 and I2). This is to allow the connection of Earth Phase Currents, Istby and Ie. With the use of Three Phase Currents one of the Earth Fault Phases is lost. The number of Overcurrent Poles can be set by the user. P&B Engineering Issue 3 9/08/2007 Page 17 ADVANCED FEEDERVISION 2 TECHNICAL MANUAL 8. Advanced Feedervision II Control Outputs. 8.1.

Advanced Feedervision II Control Inputs. The Advanced Feedervision II has 24 inputs to provide full control and indication for the breaker. The live side of each input is commoned to enable simplified wiring to the unit. However it should be noted that the common terminals are always live when power is connected to the Advanced Feedervision II and they should always be isolated prior to working on the wiring at the rear of the unit. The condition of all these inputs can be viewed at any time via the Digital Inputs page, which enables complete wire checking without the need to disconnect or even gain access to wiring. The inputs that will be used by the Advanced Feedervision II are chosen by the relay when the user chooses the position of the relay, in the Auto Transfer Scheme. Depending upon the position there might be as little as 13 digital inputs. TNC Trip. This input is an external trip input from the Local Control Panel to the relay telling it to trip. The command can originate from another relay or a switch. When the signal is received the relay will trip and open the circuit breaker. (Open = Neutral, Close = Trip). TNC Close Active In Local. This input is an external input from the Local Control Panel to the relay to close the circuit breaker associated with the relay. The input can originate from another relay or a switch. When the signal is received the relay will close the circuit breaker. (Open = Neutral, Close = Close). Local. This contact allows control of the Advanced Feedervision II and the circuit breaker to be controlled via local control (via Remote Close Terminals). It is also only possible to reset the Advanced Feedervision II after a fault from the front panel without authorisation if the Advanced Feedervision II is in the Local control mode. (Open = Neutral, Close = Local). Remote. This contact allows control of the Advanced Feedervision II and the circuit breaker to be controlled via remote control either via the direct wired PLC inputs or via the RS485 serial link. This input is mutually exclusive to the Local input mentioned above. They should not be in the same state of open or close, if the Local input is closed then the Remote input must be open and vice versa. If they are in the same state a trip or alarm is called depending upon the setting of the Local/Remote Protection Function (Number 14) see section 14.5.2. (Open = Neutral, Close = Remote).

Page No. 26 Issue 3 9/08/2007 P&B Engineering ADVANCED FEEDERVISION 2 TECHNICAL MANUAL 10. Trip Circuit Supervision. The trip circuit encompasses more than just the relay. It passes through external components such as fuses, links, relay contacts, auxiliary switch contact and others. Errors in any of these external components could lead to a trip not being called and a breaker remaining closed. To protect against these failures the Advanced Feedervision II has two trip circuit supervision input circuits, one to monitor the trip relay and one to monitor the circuit breaker. Should they both read the same input, i.e. a trip has been called and the breaker is closed, the assigned output relay changes state. TYPICAL CONNECTIONS FOR SUPERVISION ELEMENTS -ve +ve EXTRA CONTACTS IN PARALLEL TRIP CONTACT(S) CB AUX SWITCH TRIP COIL TC TCS 2 TCS 1 45 46 47 48 FEEDERVISION Trip Circuit Supervision The digital outputs provided by the Trip Circuit Supervision are then fed into an indication lamp or as a Digital Input to the Advanced Feedervision II, under the name of External Fault. The Trip Circuit Supervision Output Relays are Fail Safe. This means that on power up the relay change state. Therefore in the situation where power is lost to the Advanced Feedervision II an indication is given through the Trip Circuit. The output relays will enter an unhealthy state if one or both of the TCS Inputs are closed or if power is lost to the relay. The relays will only go back to a healthy state if both the inputs are open. P&B Engineering Issue 3 9/08/2007 Page 27 ADVANCED FEEDERVISION 2 TECHNICAL MANUAL 11. Advanced Feedervision II Serial Port The Serial Port supplied with Advanced Feedervision II as standard utilises a half duplex RS485 protocol allowing up to 32 Advanced Feedervision II's to be daisy-chained together with a single shielded twisted pair cable. The Advanced Feedervision II in addition to its very comprehensive protection and control features has been equipped with a very powerful data communications system. This extends its boundaries far beyond a feeder protection controller into the realms of a complete feeder management system. It provides a high-speed data acquisition to supervisory computers to form a complete feeder management system. Each Advanced Feedervision II can be connected to an isolated data highway using RS485 communications. Up to 32 Advanced Feedervision II units can be connected to each data highway. The host system can interrogate the unit to monitor feeder status, load conditions, historical data and fault data as well as reset fault/alarm conditions. The Advanced Feedervision II is available with P&B Goldstart protocol installed for use with P&B’s Goldstart Integrated Protection, Control & Monitoring System or with a Slave implementation of Modbus RTU protocol for small systems where data concentration is not required. Full details of the protocols, device mapping and XXCell system are contained in the P&B Integrated Protection & Control System Integrators Manual, available on request. Page No. 28 Issue 3 9/08/2007 P&B Engineering ADVANCED FEEDERVISION 2 TECHNICAL MANUAL 12. Advanced Feedervision II Faceplate Functions. The Advanced Feedervision II Faceplate has been designed to provide display and access to all the required information an operator may require. This is achieved by using a 2 tri-colour LED’s, a fully graphic LCD display and 4 function keys. This eliminates the need for additional indication devices on the front of the switch gear panel such as Lamps, Ammeter, Voltmeter, Hours Run Indicator, Operations Counter, etc. which helps reduce the cost of the switch gear panel and gives improved reliability by reduction of separate components. 12.1. LED Status. The LED's on the front of the Advanced Feedervision II operates as follows: LED Colour Green Yellow Red P&B Engineering Left LED - Feeder Status Open Tripped Closed Issue 3 9/08/2007 Right LED - Fault Status Healthy Alarm Fault Page 29 ADVANCED FEEDERVISION 2 TECHNICAL MANUAL 13.

It can either be set to Enabled or Disabled, with a default setting of Enabled Feeder Number. This setting range 1-32 with a default setting of 1, identifies the Advanced Feedervision II unit to the XCell unit to which the RS485 Data Highway is connected, and is also required to be set if the setting software is to be used. Baud Rate. This setting range 9600, 19200 or 38400 Bits/Second with a default setting of 9600, determines the speed of communications. Serial Delay. This setting range 1ms to 250ms determines the delay between the request for information from the XCell and the sending of information through the communication link by the Advanced Feedervision II. This is in steps of 1ms in the range 1 to 10 ms and in steps of 10ms in the range 10 to 250ms. Max Fast Scan. This setting, range 0-30 sec, in steps of 1 sec, determines the Fast Scan Update Time, i.e. the timeframe that the PCX asks for the Fast Scan Data from the relay. Fast Scan 1-3. This setting range 0-126 in steps of 1 determines the data that is sent to the XXCell during the fast scan cycle. Other details are read during a normal scan, which is done less often. The settings refer to the addresses of the data in the software of the relay. Note. The above settings are used for all positions of the Advanced Feedervision II in the Auto Transfer Scheme.

The relay can be set to AFV1 (Incomer 1 Protection), AFV2 (Bus Coupler Protection), AFV3 (Incomer 2 Protection), AFV4 (Bus Coupler Controller) or AFV5 (Controller). When this is set it determine what is assigned to the Digital Inputs, the Relay Outputs, the Feeder Settings and the Protection Functions used. For more details on the Auto Transfer Scheme see section 16. Overcurrent Poles. This setting determines the current inputs to the Advanced Feedervision II. This can be set to either 3+1, (3 Phase Currents and 1 Earth Fault Current) or 2+2 (2 Phase Currents, third is calculated. and 2 Earth Fault Currents). This will then effect some of the Protection Functions (i.e. Earth Fault 2 is not available when in 3+1 mode) Synchronisation This setting, which can be set to Ph/n or Ph/Ph indicates to the Advanced Feedervision II which way the synchronisation voltage is connected. Voltage. This setting range, 50-49500V in steps of 1V with default setting of 240V, enables the Advanced Feedervision II to display the measured voltages in exact volts. The setting range shown on the display is actually 50-150% of the VT Primary, displayed in volts. This means that the VT Primary should be set before the Voltage, as an increase in the VT Primary will automatically increase the Voltage Range. As the VT Primary is increased so is the Line Voltage range, with a max-min of 50-49500V. VT Primary. This setting, range 100V to 33000V with a default setting of 415V, should be set to the primary rating of the voltage transformer. This is in steps of 1V. VT Secondary. This setting, range 100V to 415V with a default setting of 100V, should be set to the secondary rating of the voltage transformer. This is in steps of 1V. P&B Engineering Issue 3 9/08/2007 Page 49 ADVANCED FEEDERVISION 2 TECHNICAL MANUAL CT Primary. This setting, range 50-4000 Amps with a default setting of 100A, determines the primary ratio for the phase current transformers. This is in steps of 5 Amps in the range 50 to 100 Amps, in steps of 10 Amps in the range 100 to 1000 Amps and in steps of 50 Amps in the range 1000 to 4000 Amps. Constant Current Rating. Range 50-100%, in steps of 5%, determines the current being controlled by the breaker. The Constant Current Rating (CCR) is a percentage of the CT Primary. Earth Fault 1 Primary. This setting range 50-4000 Amps determines the primary ratio of the core balance earth fault CT if used. If a residual connection of phase CT's is used this setting must be the same as for the phase CT primary setting. This is in steps of 5 Amps in the range 50 to 100 Amps, in steps of 10 Amps in the range 100 to 1000Amps and in steps of 50 Amps in the range 1000 to 4000 Amps. Earth Fault 2 Primary. This setting range 50-4000 Amps determines the primary ratio of the core balance standby earth fault CT, if used. If a residual connection of phase CT's is used this setting must be the same as for the phase CT primary setting. This is in steps of 5 Amps in the range 50 to 100 Amps, in steps of 10 Amps in the range 100 to 1000 Amps and in steps of 50 Amps in the range 1000 to 4000 Amps. kW Sample Period. This setting range 1-60 minutes in steps of 1 minute determines the period over which a measurement is taken for the Kilowatt Hours value. Dead Bus Level This setting determines the voltage level on the Bus for the Advanced Feedervision II to recognise the Bus as being in an Unhealthy or Dead state. The range is from 15% to 50% in steps of 5%, and is read from the Protection Function Dead Bus Setting, and therefore cannot be changed here. Page No. 50 Issue 3 9/08/2007 P&B Engineering ADVANCED FEEDERVISION 2 TECHNICAL MANUAL Parallel Time. This is the maximum time that the three circuit breakers (Incomer 1, Incomer 2 and Bus Coupler) can be closed at the same time during the Auto Transfer Process. The range of the settings is between 0.1 seconds and 1.0 seconds in steps of 0.1 seconds. HT1 Delay. This is the minimum time between the HT Circuit Breaker on Incomer 1 opening and the Auto Transfer Scheme taking place. The range of the settings is between 0.5 seconds and 5.0 seconds in steps of 0.1 seconds. HT2 Delay. This is the minimum time between the HT Circuit Breaker on Incomer 2 opening and the Auto Transfer Scheme taking place.

(Those In Capitals Above) Close. On receiving a command to close the circuit breaker this output relay closes, thus sending a close signal to the corresponding circuit breaker on the appropriate Incomer. This signal remains closed until the relay is informed that the breaker has changed state. The relay determines the status of the breaker via the digital input "Circuit Breaker on IC#". Once the status of this digital input has changed the output relay opens. In the case where no change of breaker status is detected, the output relay remains closed until the time specified in the Breaker Fail Protection Function has elapsed. Close IC1. On receiving a command to close the circuit breaker this output relay closes, thus sending a close signal to the circuit breaker on the Incomer 1. This signal remains closed until the relay is informed that the breaker has changed state. The relay determines the status of the breaker via the digital input "Circuit Breaker on IC#". Once the status of this digital input has changed the output relay opens. In the case where no change of breaker status is detected, the output relay remains closed until the time specified in the Breaker Fail Protection Function has elapsed. Page No. 54 Issue 3 9/08/2007 P&B Engineering ADVANCED FEEDERVISION 2 TECHNICAL MANUAL Trip. This output is used to trip the circuit breaker and follows the same pattern as above. I.e. when a trip command is received the output relay closes and remains closed until the breaker is seen to open via the "Circuit Breaker on IC#" input or the time specified in the Breaker Fail Protection Function has elapsed. Serial. This is the close command to the Circuit Breaker that is activated through the serial link, i.e. a command from the DCS. If two seconds after a close command is given and the circuit breaker remains open then the Breaker Fail Protection function is activated. Trip IC1. This output is used to trip the circuit breaker on Incomer 1. If two seconds after a Trip command is given and the circuit breaker has not tripped then the Incomer 1 Breaker Fail Protection function is activated. Trip IC2. This output is used to trip the circuit breaker on Incomer 2. If two seconds after a Trip command is given and the circuit breaker has not tripped then the Incomer 2 Breaker Fail Protection function is activated. Auto. This output closes when an Auto Transfer is possible. Manual. This output closes when a Manual Transfer is possible. Auto Alarm. This output closes when an Auto Transfer Failure has occurred. Programmable Outputs. Not Used. This option switches off the use that particular output relay. Warn 1. This output relay is closed when a Protection Function with the Warn 1 option Enabled has had its trip value exceeded. This means that a trip or alarm is imminent once the trip delay has expired. Warn 2. This output relay is closed when a Protection Function with the Warn 2 option Enabled has had its trip value exceeded. This means that a trip or alarm is imminent once the trip delay has expired. Alarm. This output relay is activated when a Protection Function with the Alarm Enabled has tripped. Indicator 1-5 These output relays are closed when a Protection Function with one of the Indicator 1-5 option Enabled has tripped. P&B Engineering Issue 3 9/08/2007 Page 55 ADVANCED FEEDERVISION 2 TECHNICAL MANUAL Alarm Fail-Safe. This output relay is the opposite of the alarm relay. It is used as a fail-safe option on the Advanced Feedervision II. Trip. This output relay is activated when a Protection Function with the Trip Enabled has tripped. Trip Fail-Safe. This output relay is the opposite of the trip relay. It is used as a fail-safe option on the Advanced Feedervision II. Indicator 1-5 Fail-Safe. This output relay is the opposite of the Indicator 1-5 relays. It is used as a fail-safe option on the Advanced Feedervision II. DCS Available. This output indicates that the relay is able to follow commands from the DCS, through the serial port. 14.5. Protection Settings In most of the Protection Functions there is the possibility to set the Trip Level and the Trip Time. When the Trip Level has been exceeded by an input to the Advanced Feedervision II a warning is given, if enabled. This means that a trip is imminent. Once the Trip level has been exceeded the Trip Time is used as a delay before a trip or alarm is called, depending upon how the function has been set up. 14.5.1. Protection Features. In the Protection Functions there is the possibility to enable or disable the Features that follow. Function. When Enabled this setting activates the Protection Function associated with it. It also allows the user to set other parameters associated with the Protection Function such as the Trip Level and the Trip Delay. It also displays a 'tick' next to the Protection Function in the Protection Settings Screen on the relay to indicate to the user that the Protection Function is Enabled. When this is set to Disable the rest of the settings associated with the Protection Function, such as Trip Delay, is faded out and therefore cannot be set. Warn 1. When set to Enabled this setting activates the Output Relay that is programmed to Warn 1 indicating that a trip is imminent after the trip time has been exceeded. It is activated when the Trip Level has been exceeded. Page No. 56 Issue 3 9/08/2007 P&B Engineering ADVANCED FEEDERVISION 2 TECHNICAL MANUAL Warn 2. When set to Enabled this setting activates the Output Relay that is programmed to Warn 2 indicating that a trip is imminent after the trip time has been exceeded. It is activated when the Trip Level has been exceeded. Alarm. When set to Enabled this will call an alarm when the Trip Time is exceeded. This will then cause the Alarm Relay to change states, if one of the Output Relays is set to Alarm. It also displays an 'A' next to the Protection Function in the Protection Settings Screen to indicate to the user that the Alarm option has been Enabled. When set to Disabled the Alarm for that Protection Function will not be called. Trip. When set to Enabled this will call a Trip when the Trip Time is exceeded. This will then cause the Trip Relay to change states, if one of the Output Relays is set to Trip. It also displays an 'T' next to the Protection Function in the Protection Settings Screen to indicate to the user that the Trip option has been Enabled. When set to Disabled the Trip for that Protection Function will not be called. Indicator 1. When set to Enabled this setting activates the Output Relay that is programmed to Indicator 1 when the trip time is exceeded. Indicator 2. When set to Enabled this setting activates the Output Relay that is programmed to Indicator 2 when the trip time is exceeded. Indicator 3. When set to Enabled this setting activates the Output Relay that is programmed to Indicator 3 when the trip time is exceeded. Indicator 4. When set to Enabled this setting activates the Output Relay that is programmed to Indicator 4 when the trip time is exceeded. Indicator 5. When set to Enabled this setting activates the Output Relay that is programmed to Indicator 5 when the trip time is exceeded. P&B Engineering Issue 3 9/08/2007 Page 57 ADVANCED FEEDERVISION 2 TECHNICAL MANUAL Inhibit. When set to Enabled this setting inhibits any control function, such as open, close and auto transfer to operate. One disabled a control function can be carried out. Auto Reset. This option, when enabled, automatically resets the Fault when the situation that caused the trip has been removed. Panel-Reset. This option, when Enabled, allows a reset of a fault to be accomplished from the front panel of the relay when the situation that caused the trip has been removed. Serial-Reset. This option, when Enabled, allows a reset of a fault to be accomplished through the serial link of the relay when the situation that caused the trip has been removed. Note. When the Position of the relay is set to AFV 1, AFV 2, AFV 3 and AFV 5 all the features are shown. When the Position of the relay is set to AFV4 only the following protection features are used: Function, Alarm, Trip, Inhibit, Auto Reset, Panel Reset and Serial Reset. Page No. 58 Issue 3 9/08/2007 P&B Engineering ADVANCED FEEDERVISION 2 TECHNICAL MANUAL 14.5.2. Protection Functions. There are 46 possible Protection Functions for the Advanced Feedervision II. The Functions used depends upon the position of the relay in the Auto Transfer Scheme. Each Function is given a function number, 1 to 45, so it is therefore easier to show which Protection Functions are assigned to which Position of the Advanced Feedervision II.

In the Unit Settings of the Advanced Feedervision II many of the parameters shown are not for setting, some are for providing information to the user. They are as follows: Software Version. This displays the software version running on the relay as well as a software date for that version. Unit ID. This shows the serial number of the relay. This serial number should be quoted along with the software version when corresponding to P&B Engineering about the relay. Password. The Advanced Feedervision II provides a password for security, which can be Enabled or Disabled. When Enabled the user must enter the Password when they wish to enter the setting part of the Advanced Feedervision II's menu. This is not the password that allows the changing of the Position. That password is always Enabled and cannot be changed. P&B Engineering Issue 3 9/08/2007 Page 71 ADVANCED FEEDERVISION 2 TECHNICAL MANUAL Change Password. When first used the Advanced Feedervision II has a default password of 'BB'. It is recommended for security that the password be changed. This is done by selecting the Change Password Screen. The user is then able to enter a password of up to 5 characters in length. The characters A-Z being available for the user to choose for their password. Customise Strings. Although this setting can be set in the unit setting it refers to a setting that is with regards to the Digital Inputs (See Section 14.3) LCD Backlight and LCD Contrast. These functions allow the user to change the display contrast and backlight. Set Default Page. This allows the user to define which of the Measured Values are displayed on the screen of the relay when the relay defaults after the Default Return Time (See below). The options available are:I1, I2, I3 Ie, Istby (Just Ie if 3 Pole Overcurrent is chosen). Pwr1, Pwr2, Pwr3 PF1, PF2, PF3 V1, V2, V3 V12, V23, V31 The value shown in the default screen is set by selecting the chosen Measured Value, using the DISPLAY SCROLL button, on the main screen. Then going to this setting and pressing the SELECT button it will save the chosen input. Default Return Time. If the Motorvision is not being accessed using the buttons on the front of the relay after a predetermined time the relay will default to the Initial Screen. If you are accessing the relay you will not want it to default to another Screen when your back is turned. In this setting you can control that feature. You are able to switch off the return feature or specify a time of 1,2,4 or 8 minutes for the delay before the return to the Initial Screen. User Calibration This is used to calibrate the relay and is only used at the factory. If a customer wishes to recalibrate the relay they should contact P&B Engineering.

Auto Transfer Scheme. 16.1. Auto Transfer Scheme. The scheme is based on an arrangement of two incoming feeders and one bus coupler and allows for; auto changeover in the case of an undervoltage fault on one of the incomers and also for manual momentary paralleling. Before the development of the Advanced Feedervision II the only way to accomplish an Auto Transfer Scheme was to utilise up to thirty different relays, each one accomplishing a single task required for the Scheme. 16.2. Auto Transfer Scheme Using Advanced Feedervision II Relays. The Auto Transfer Scheme using Advanced Feedervision II Relays has been developed by P&B Engineering to meet the general requirements of Reliance Industries Ltd. (India) and is based on the EXXON standard. The functions of the Advanced Feedervision II Relays are fully field programmable and therefore the requirements of other schemes can be met as required. The scheme as above is realised using four Advanced Feedervision II Relays as shown in the diagram on the next page. A more simplified Auto Transfer Scheme can be realised with just three Advanced Feedervision IIs, those in Position AFV1, AFV3 and AFV5. It is only recommended for certain schemes and will not be explained in detail in this manual. 16.3 Incomer 1 Protection, Position AFV1. Two Advanced Feedervision II Relays are used, AFV1 and AFV3, one on each incoming feeder, for; breaker control and monitoring, protection, undervoltage detection and incorporation of external plant signals. Trip and alarm signals from upstream protection devices associated with the HV circuit and / or transformer such as Buchholz and Restricted Earth Fault relays are handled by these relays. These Advanced Feedervision II Relays can act as a lockout for the upstream protection devices connected as digital inputs. The Advanced Feedervision II set to Position AFV1 is used to protect Incomer 1. 16.4. Incomer 2 Protection, Position AFV3. This is the second Advanced Feedervision II to be used for protecting the incoming feeder. This relay is used to protect Incomer 2.

Bus Coupler Protection, Position AFV2. The Advanced Feedervision II Relay in Position AFV2 is used, on the bus coupler for; protection, dead bus detection (On Bus A) and check synchronisation. 16.6 Bus Coupler Controller, Position AFV4. The Advanced Feedervision II Relay in Position AFV4 operates as a controller which; provides breaker control and monitoring for healthy bus (On BUS B) and the bus coupler circuit breaker, marshals the signals from the other three relays, provides the timing functions and interfaces to the local manual control switches. 16.7. Scheme operation. In the case of one incomer being under voltage the associated incomer circuit breaker is opened and the bus coupler circuit breaker is closed. After a time delay, which allows for load shedding, both sets of outgoing feeders (Bus A and B) are fed from the same incomer. All the required functions including; the time delays to allow for load shedding, the check sync. function, the dead bus detection and incorporation of signals from upstream protection devices are handled by the Advanced Feedervision II Relays. In the case of both incomers under voltage the Advanced Feedervision II relays detect a system undervoltage and neither incomer circuit breaker is opened and the bus coupler circuit breaker remains open. To return to the normal condition, of both incomer circuit breakers being closed and the bus coupler circuit breaker being open, or one of the incomers being taken out of service for maintenance, manual momentary paralleling is used. In this case the circuit breaker that is open is closed and one of the remaining two is opened after a delay. All the required functions including; the time delays, the check sync. function, the dead bus detection and incorporation of signals from Auto / Manual and trip selector switches are handled by the Advanced Feedervision II Relays. Conclusion. The P&B Advanced Feedervision II Relay provides an integrated solution to the protection, control and monitoring of Low Voltage feeders. Its sophisticated control functions allow complex auto transfer schemes to be realised with few external devices. The Advanced Feedervision II Relays integrates many functions that were previously achieved using separate protection devices and control products connected as a system. Advanced Feedervision II Relays used in the above auto transfer scheme eliminate the cost of separate protection devices and control products. P&B Engineering Issue 3 9/8/2007 Page 77
