Distrubance recording
Recording of sampled values of analog measurement signals and logic states.
Through parameter setting, it is possible to choose:
# the events that will trigger a record
# the recording time prior to the occurrence of the event
# the number and duration of records (series 40 only).
The values are displayed as primary values with the
related units: A,V,Hz,°C,°F, W, …
Current
# RMS current for each of the 3 phases in the circuit,
taking into account harmonics up to number 17
# residual current.
Average current and peak demand current
# average current on each of the 3 phases
# greatest average current on each of the 3 phases
(peak demand current).
The peak demand currents give the current consumed
at the time of peak loads.
The average current is calculated over a period that
may be parameterized from 5 to 60 mn, and may be
reset to zero.
Voltage
phase-to-neutral voltages V1, V2, V3

Protection functions
Description
Current protection functions
Directional earth fault (ANSI 67N/67NC)
It has 2 types of characteristics:
# type 1, according to Io protection
# type 2, according to Io magnitude.
It can operate on impedant, isolated or compensated neutral grounding systems.
The type 1 units allow the detection of restriking faults.
The protection includes two units:
# definite time (DT)
# IDMT (16 types of IDMT curves) (type 2 only)
# instantaneous or time-delayed.
The type 2 units have a reset time setting that allows:
# detection of restriking faults
# coordination with electromechanical relays.
Phase overcurrent (ANSI 50/51)
Three-phase protection against overloads and phaseto-phase short-circuits. The protection comprises four
units:
# definite time (DT)
# IDMT (16 types of IDMT curves)
# instantaneous or time-delayed.
Each unit has a reset time setting that allows:
# detection of restriking faults
# coordination with electromechanical relays.
Earth fault (ANSI 50N/51N or 50G/51G)
Earth fault protection.
Earth faults may be detected according to parameter
setting by:
# current transformers on the three phases (3I sum)
# a special core balance CT, CSH120 or CSH200,
according to the required diameter; this method
provides the highest sensitivity. The choice of
parameterizable ratings provides a very wide setting
range.
# a current transformer (1 A or 5 A), combined with a
CSH30 interposing ring CT.
The protection comprises four units:
# definite time (DT)
# IDMT (16 types of IDMT curves)
# instantaneous or time-delayed.
Each unit has a reset time setting that allows:
# detection of restriking faults
# coordination with electromechanical relays.
It also has a harmonic 2 restraint in order to ensure
stability upon transformer energizing.
Breaker failure (ANSI 50 BF)
Backup protection that delivers a tripping order to the
upstream or adjacent breakers should the breaker that
is being commanded fail to trip, detected by
measurement of the phase current after a tripping
order.
Negative sequence / unbalance (ANSI 46)
Protection against phase unbalance.
Sensitive protection to detect 2-phase faults at the end
of long feeders.
Protection of equipment against temperature build-up
caused by an unbalanced supply or the inversion or
loss of a phase and against phase current unbalance.
IDMT or definite time characteristics.
Directional current
protection functions
Directional phase overcurrent (ANSI 67)
This protection function is 3-phase. It comprises a
phase overcurrent function associated with direction
detection. It picks up if the phase overcurrent function
in the chosen direction (line or busbar) is activated for
at least one of the three phases. It operates as definite
time or IDMT. It is insensitive to the loss of
measurement voltage at the time of the fault.
12
Power protection functions
Active overpower (ANSI 32P)
This protection function is activated if the active power flowing in one direction or the
other according to the application (supplied or absorbed) is greater than the set point.
Machine protection functions
Thermal overload (ANSI 49)
Protection of equipment against thermal damage caused by overloads.
The thermal capacity used is calculated according to a mathematical model which
takes into account:
# RMS current values
# ambient temperature.
The function comprises:
# an adjustable alarm setting
# an adjustable trip setting
5 transformer application.
The model takes into account the transformer heat rise and cooling time constants
according to whether natural or forced ventilation is used (ONAN, ONAF) via a logic
input.
5 motor application.
The model takes into account:
- two time constants: the heat rise time constant, used when the motor is running,
and the cooling time constant, used when the motor is stopped,
- effect of negative sequence current on rotor heating.
An additional setting may be used to adapt the protection to the motor thermal
withstand indicated by the experimental hot and cold curves given by the machine
manufacturer.
The thermal protection function may be inhibited by a logic input when this is required
by the process running conditions.
Phase undercurrent (ANSI 37)
Protection of pumps against the consequences of a loss of priming.
The protection function detects time-delayed current drops that correspond to motor
no-load operation, characteristic of the loss of pump priming.
Locked rotor / excessive starting time (ANSI 48/51LR)
Protection of motors that are liable to start with overloads or insufficient supply
voltage and/or that drive loads that are liable to jam (e.g. crushers).
The locked rotor function is an overcurrent protection function that is only confirmed
after a time delay that corresponds to the normal starting time.
Starts per hour (ANSI 66)
Protection against overheating caused by too frequent starts.
Checking of the number of:
# starts per hour (or adjustable time period)
# consecutive starts.
The protection inhibits motor energizing for a preset time period when the
permissible limits have been reached.
Motor restarting may be taken into account by a logic input.
Schneider Electric
Protection functions
Description
Thermostat, Buchholz, gas, pressure, temperature detection
Protection of transformers against temperature rise and internal faults via logic inputs
linked to devices integrated in the equipment.
Temperature monitoring (RTDs) (ANSI 38/49T)
Protection against abnormal overheating of motor windings and/or bearings
equipped with RTDs.
The protection includes 2 independent set points that are adjustable for each RTD.
Positive sequence undervoltage (ANSI 27D) (ANSI 47)
Motor protection against malfunctioning due to insufficient or unbalanced supply
voltage.
Detection of reverse rotation direction.
In order for this protection to be used, voltage transformers must be connected to
Sepam 1000+ to measure U21 and U32.
Remanent undervoltage (ANSI 27R)
Monitoring of the clearing of voltage sustained by rotating machines after circuit
opening.
The protection is used to prevent transient electrical and mechanical phenomena
that are caused by fast re-energizing of motors.
It monitors phase-to-phase voltage U21 or phase-to-neutral voltage V1.
Voltage protection functions
Phase-to-phase undervoltage (ANSI 27)
Protection used either for automated functions (transfer, load shedding) or to protect
motors against undervoltage. The protection function monitors the drop in each of the
phase-to-phase voltages being metered.
Phase-to-neutral undervoltage (ANSI 27S)
Protection used to detect phase-to-earth faults (isolated neutral systems).
Phase-to-phase overvoltage (ANSI 59)
Protection against abnormally high voltage or checking that there is sufficient voltage
for power supply changeover. It operates with phase-to-phase voltage (series 20 and
series 40) or with phase-to-neutral voltage (series 40 only).
Neutral voltage displacement (ANSI 59N)
Detection of insulation faults in isolated neutral systems by measurement of neutral
voltage displacement. The protection function is generally associated with
transformer incomer or busbar protection.
The function includes 2 set points.
Negative sequence overvoltage (ANSI 47)
Protection against phase unbalance resulting from distant faults, a phase inversion
or unbalanced power supply.
Frequency protection functions
Overfrequency (ANSI 81H)
Protection against abnormally high frequency.
Underfrequency (ANSI 81L)
Detection of variances with respect to the rated frequency, in order to maintain a high
quality power supply. The protection may be used for overall tripping or for load
shedding.

Control and monitoring
Description
Sepam 1000+ performs the basic control and
monitoring functions necessary for the operation of the
electrical network, thereby reducing the need for
auxiliary relays.
The control and monitoring functions may be
parameterized using the SFT 2841 software tool,
however each type of Sepam has parameter setting by
default which allows easier commissioning in the most
frequent cases of use.
Latching / acknowledgment (ANSI 86)
Output relay latching may be parameterized. Latched tripping orders are stored and
must be acknowledged in order for the device to be put back into service. The user
acknowledges via the keypad or remotely via a logic input or the communication link.
Latching is stored in the event of a power outage.
Two control modes are available
# integrated circuit breaker control.
This logical function processes all the circuit breaker
closing and tripping conditions based on position
information, external control orders and protection,
recloser, etc.
# individual parameter setting of output relays.
Control of output relays according to an assignment
matrix.
Breaking device control
# Sepam is used to control breaking devices equipped
with different types of closing and tripping coils:
5 circuit breakers with shunt trip or undervoltage trip
units (parameter setting on front panel (1) or via
SFT 2841)
5 latching contactors with shunt-trip units.
Output relay control (standard or fail-safe) may be
parameterized.
By default, the program logic is adapted to control a
circuit breaker with a shunt trip unit.
# open and close control via the communication link
# inhibition of closing (ANSI 69)
Sepam inhibits the closing of the circuit breaker or
contactor according to the operating conditions.
# remote tripping
Remote control of the tripping of the circuit breaker or
contactor is possible via a logic input or via the
communication link.
# inhibition of remote control
A logic input inhibits the remote closing of the circuit
breaker via the communication link.
Switching of setting groups
Used to switch from one group of (directionnal) phase
overcurrent and earth fault protection settings to
another group of settings. Switching may be performed
by a logic input or via the communication link.
Inhibition of thermal protection
Thermal protection tripping may be inhibited via a logic
input.
Re-acceleration
Allows a logic input to take into account the restarting
of an unstopped motor.
Logic discrimination (ANSI 68)
This function allows quick, selective tripping of the
definite time or IDMT phase overcurrent and earth fault
protection relays, without requiring the use of time
intervals between upstream and downstream
protection devices. The downstream relay transmits a
blocking input signal if the protection device set points
are exceeded.
The upstream relay receives the blocking input signal
on the logic input used for the inhibition function. A
saving mechanism ensures the operation of the
protection in the event of an inhibition link failure.
Annunciation (ANSI 30)
Sepam indicates the appearance of alarms by:
# signal lamps on the front panel
# messages on the display.
The addressing of the signal lamps may be parameterized.
The sequence is as follows (advanced UMI):
# when an event appears, the signal lamp goes on and the related message is
displayed
# the user presses the “clear” key to erase the message
# after the fault disappears and the “reset”, key is pressed, the signal lamp goes off
and/or the message is erased and the protection is reset
# the list of alarm messages remains accessible (
key) and may be erased by
pressing the “clear” key.
Remote annunciation
Used to transfer information via the communication link.
Information such as circuit breaker position, SF6 fault alarm, etc.
Trip circuit supervision
Detects trip circuit faults (shunt trip units). Detects open/closed position discrepancy
faults (undervoltage trip units).
Watchdog
Indicates Sepam unavailability via output O4.
Output relay testing
This function is used to activate each output relay (1).
Logical parameter setting (Boolean equation editor)
Used for logical grouping of protection function outputs and logic inputs by the AND,
OR, NO functions in order to supply new states that can activate a logic output, a
signal lamp, an alarm message or a remote indication.

E65568
Example of advanced UMI with standard assignment of signal
lamps.
The Sepam 1000+ can be set:
# via the front panel when Sepam 1000+ is equipped with the advanced UMI
function. Function keys (blue) may be used to navigate in the menu and to scroll and
accept the displayed values.
Main functions performed:
5 changing of passwords
5 entry of general settings
5 entry of protection settings
# via a PC equipped with the SFT 2841 software tool connected to the front panel
for all types of Sepam 1000+.
Menus guide the user through the different phases of parameter and protection
setting by a series of windows suited to each operation.
The SFT 2841 software tool may be used for Sepam 1000+ parameter and
protection setting in connected or unconnected mode. The unconnected mode
allows all the parameter settings to be prepared ahead of time and loaded in a single
operation when the Sepam 1000+ is connected on site (downloading).
Main functions performed by the SFT 2841:
# changing of passwords
# entry of general settings (ratings, integration period, …)
# entry of protection settings
# changing of program logic assignments
# enabling/disabling of file saving functions.
Example of phase overcurrent protection setting screen
(series 20).
E65575
Program logic parameter setting
Program logic parameter setting consists mainly of assigning the data transmitted by
the protection functions to the signal lamps and output relays. This is done by
entering the data in the "control matrix" of the SFT 2841 software tool.
Example of parameter setting (serieS 20).

Program logic
Parameter and protection
settings
Each Sepam 1000+ has program logic by default according to the chosen type
(S20, S40, T20,…) as well as messages for the different signal lamps.
The functions are assigned according to the most frequent use of the unit. The
parameter setting and/or marking may be customized if required using the SFT 2841
software tool.
