See Appendix C. 2. Application The Optical interface unit G1IF1 provides a connection between a fibre optic communications channel and a switched telecommunications network. It is applied in the protection signalling channel of the GRL100 line differential relay, allowing two GRL100 relays to communicate over a telecommunications channel. The G1IF1 provides an interface for connection of the fibre optic protection signalling port of the GRL100 relay to remote multiplexing equipment having a standard CCITT G703 or X.21 type interface to the electrical connections of a telecommunications system. Figure 2.1 illustrates the application of the G1IF1 unit. GRL100 Line Diff. Relay Switched Telecomms Muliplexer G1IF1 CCITT G703 or X.21 Interface Fibre Optic Cable Figure 2.1 Application of G1IF1 Unit In most situations the telecommunications equipment is remote from the protection equipment in the substation. The G1IF1 unit is normally located close to the multiplexer and may be up to 2km away from the GRL100 relay. The fibre optic cable must be either 50/125µm (for distances up to 1km) or 62.5/125µm (for distances up to 2km) and should be terminated with standard ST type connectors. The G1IF1 is connected to the switched telecommunications network via a multiplexer. The interface is defined according to the CCITT G703 or X.21 standard. The connections should be made using shielded, twisted pair cable. 4 6 F 2 S 0 7 5 5 3. Description 3.1 General Description Figure 3.1 illustrates the operation of the Optical interface unit. The GRL100 relay and the telecommunications multiplexer are illustrated to facilitate the explanation. The G1IF1 unit provides three fibre optic connectors. The transmitter / receiver pair TX/RX connect to the GRL protection signalling channel. The clock transmitter CLK can be used to transmit the CCITT-G703-1.2.3(1.2.2) or X.21 timing signal, although it is not required in applications such as this, where the receive signal from the G703-1.2.3(1.2.2) or X.21 is synchronized to the clock signal. The CLK is not used for the CCITT-G703-1.2.1 interface. An additional connection point, labelled SPARE (not shown in Figure 3.1), can be used for fitting of a spare fibre optic cable. Optical to electrical and electrical to optical conversion is performed on the transmit and receive signals from the GRL100 relay respectively. CMI type encoding is used for the optical signals. CMI encoding always results in a 50% duty factor, making the signals easy to check during commissioning. Code conversion is performed for connection to the CCITT-G703 or X.21 interface. G703 or X.21 is a synchronous interface, and provides a 64kHz timing signal, which the G1IF1 uses for synchronisation. The connections to the G703 or X.21 interface use balanced drivers and receivers in accordance with the G703 or RS422A/V.11 standard. 50/125µm 62.5/125µm Fibre GRL100 Serial Comms Interface E/O G1IF1 O/E TX RX Telecomms Muliplexer Code Conversion 64kHz Sync.

Operation of G1IF1 Unit 5 6 F 2 S 0 7 5 5 3.2 Electrical Connections A 12-way ring terminal, connector TB1 of G1IF1 provides connections for the auxiliary dc supply as well as test points for the telecommunications channel. The G1IF1-01 provides the additional X.21 connector is a 15-way DIN type. The G1IF1 auxiliary dc supply input has a nominal 48V rating as standard for communications equipment. However the G1IF1 can also be provided with dc 110/125V rating or dc 220/250V rating for 110/125V or 220/250V substation battery supplies. The connections to the G1IF1-01 are shown in Figure 3.2 (a), not including the test points. The figure also illustrates the functions of three removable links. The X.21 interface circuit is designed for 500V isolation against the rest of the system. However, it may not be desirable to leave the common connection floating, particularly where high levels of interference are expected. Therefore the X.21 common can be tied via a 10kΩ resistance to the frame ground, by fitting link J1. Alternatively, the fitting of links JIG and JFG connects the X.21 common directly to the frame ground. It is recommended that a shielded cable be used for the X.21 interface. The shield should be tied directly to the frame ground by the fitting of link JFG.

Table 3.2 details the labels, colours and functions associated with each LED. Table 3.2 Indication LEDs 3.4 LED Label Colour Function Power Green Lit when auxiliary dc power is present TX from COM Yellow Indicates data transmission from the telecommunications channel to the GRL100 relay TX from RELAY Yellow Indicates data transmission from the GRL100 relay to the telecommunications channel CLK from COM Yellow Indicates the timing signal from the G703 or X.21 interface. Response during Communication Fail (1) When the data transmission from telecommunication multiplexer to G1IF1 is stopped: The LED “TX from COM” turns off and the data “0” is transmitted to the relay. At that time, the relay at local terminal detects a communication failure. (2) When the data transmission on fibre optic interface from the relay to G1IF1 is stopped: The LED “TX from RELAY” turns off and the send signal (the voltage between terminals TB1-6 and TB1-7) becomes “0V”. “0V” means undefined data in G703-1.2.1 and means “0” data in G703-1.2.2 / 1.2.3. (3) When the timing signal from telecommunication multiplexer to G1IF1 is stopped: The LED “CLK from COM” turns off and the data transmission on fibre optic interface from G1IF1 to the relay is stopped. The data transmission to telecommunication multiplexer is continued. The relay at the remote terminal detects a communication failure intermittently because the bit synchronising between the relay at the local terminal and telecommunication multiplexer. 10 6 F 2 S 0 7 5 5 4. Installation 4.1 Receipt of Relays On receiving the G1IF1, carry out the acceptance inspection immediately. In particular, check for damage during transportation, and if any is found, contact the vendor. Always store the unit in a clean, dry environment. 4.2 Mounting Refer to Appendix A for details of mechanical fixings. 4.3 Electrostatic Discharge CAUTION The printed circuit board (PCB) within the G1IF1 is not intended to be a removable module. Do not remove the PCB from the unit case, since electronic components on the PCB are very sensitive to electrostatic discharge. If it is absolutely essential to take the PCB out of the case, do not touch the electronic components and terminals with your bare hands. Additionally, always put the PCB in a conductive anti-static bag when storing it. 4.4 Handling Precautions A person's normal movements can easily generate electrostatic potential of several thousand volts. Discharge of these voltages into semiconductor devices when handling electronic circuits can cause serious damage, which often may not be immediately apparent but the reliability of the circuit will have been reduced. The electronic circuits are completely safe from electrostatic discharge when housed in the case. Do not expose them to risk of damage by removing the PCB unnecessarily. The unit incorporates the highest practicable protection for its semiconductor devices. However, if it becomes necessary to remove the PCB, precautions should be taken to preserve the high reliability and long life for which the equipment has been designed and manufactured. CAUTION • Before removing the PCB, ensure that you are at the same electrostatic potential as the equipment by touching the case. • Handle only the edges of the PCB. Avoid touching the electronic components, PCB surface or connectors. • Do not pass the PCB to another person without first ensuring you are both at the same electrostatic potential. Shaking hands achieves equipotential. • Place the PCB on an anti-static surface, or on a conducting surface which is at the same potential as yourself. • Do not place the PCB in a polystyrene tray. It is strongly recommended that detailed investigations on electronic circuitry should be carried out in a Special Handling Area such as described in the IEC 60747. 11 6 F 2 S 0 7 5 5 4.5 External Connections External connections to the G1IF1 are shown in section 3.2. There are three types of connection to the unit. The fibre optic connections are made with standard ST type connectors. Transmitters are of the LED type. When handling fibre optic cables, care should be taken so as not to cause damage by rough treatment or by exceeding the minimum bend radius of the fibre. The CCITT G703 interface connection is made with a ring terminal block labeled TB1. The X.21 interface connection is made with a standard 15-way DIN type connector. The power supply and safety earth connections should be made with ring-type crimp terminals to the terminal block TB1. 12 6 F 2 S 0 7 5 5 5. Commissioning and Maintenance 5.1 General The G1IF1 should be commissioned in conjunction with the GRL100 relay with which it is specified. Test personnel must be familiar with general relay testing practices and safety precautions to avoid personal injuries or equipment damage. 5.2 Precautions CAUTION • The unit is provided with a grounding terminal. Before starting the work, always make sure the unit is grounded. • Ensure that the auxiliary supply connections are properly fixed to their terminals. • Before turning on the power, check that the polarity and voltage of the power supply are correct. • Turn off the auxiliary supply before checking the interior of the unit. • While the power is on, do not mount/dismount the PCB. Failure to observe any of the precautions above may cause damage or malfunction of the unit. Refer to section 4.4 for information on handling precautions. 5.3 Preparation Test equipment The following test equipment is required for the commissioning tests. • DC power supply. • Calibrated voltmeter. Visual inspection After unpacking the product, check for any damage to the case. If there is any damage, the internal module might also have been affected. Contact the vendor. Unit ratings Check that the items described on the nameplate on the front of the unit conform to the user’s specification. The items are: unit type and model, and auxiliary DC supply voltage rating. 13 6 F 2 S 0 7 5 5 5.4 Commissioning Procedure The G1IF1 should be commissioned in conjunction with the GRL100 relay with which it is specified. Refer to the GRL100 manual for full details. It is necessary to commission both ends of the protection scheme together. Ensure that all necessary communication connections are made at each end of the protection scheme. Apply auxiliary power to both GRL100 relays and to both G1IF1 units. Any failure in communication will be indicated by the GRL100 relays. If communication is healthy then proceed with commissioning of the GRL100 relays. 5.5 Maintenance Periodic maintenance is not necessary. 14 6 F 2 S 0 7 5 5 Appendix A Outline of Optical Interface Unit 15 6 F 2 S 0 7 5 5 Dimensions and Connections 2- Φ5 TB1 TOSHIBA 1 130 195 Power TX from COM TX from RELAY CLK from COM 12 2-5×9 168 180 156 SPARE RX TX CLK X.21 66 For G1IF1-01∗∗, and G1IF1-04∗∗ only 16 6 F 2 S 0 7 5 5 Outer Case Dimensions for G1IF1-01∗∗ 4-Φ6 346 326 300 266 CROSS SITE FIBRE LINK UNIT 166 200 226 246 87 17 6 F 2 S 0 7 5 5 Outer Case Dimensions for G1RK7-0102 and -0103 (Option) 4-Φ6 346 326 300 266 OPTICAL INTERFACE UNIT 166 200 226 246 87 For G1RK7-0103 only 18 6 F 2 S 0 7 5 5 Appendix B Technical Data 19 6 F 2 S 0 7 5 5 TECHNICAL DATA Ratings DC power supply: 48Vdc 110Vdc/125Vdc 220Vdc/250Vdc (Normal range: -20% to +10% of rated voltage, superimposed AC voltage ≤ 12%, break in supply duration ≤ 20ms) Burden: less than 8W Optical Interface Operative Range: <1km with 50/125µm GI fibre (3dB/km) <2km with 62.5/125µm GI fibre (3dB/km) Wavelength: 820nm Connector Type: ST Fibre Type: 50/125µm or 62.5/125µm glass fibre 20 6 F 2 S 0 7 5 5 Environmental Performance Claims for G1IF1 Test Standards Details Atmospheric Environment Temperature IEC60068-2-1/2 Operating range: -10°C to +55°C.
