MV
The protection and control of primary substations
consists of performing the metering, protection,
control and monitoring functions required
for operation.
Sepam 2000 provides all these functions globally.
All the equipment and mechanisms that are generally
found in a MV cubicle control cabinet are replaced
by a single device which performs:
c protection,
c metering,
c control and monitoring implementing protections
and logic inputs to activate tripping and closing
outputs and the display of annunciation.

Advantages
c Indication of phase and earth fault values at the time of breaking provides
the operator with useful assistance in determining the causes and seriousness
of faults.
c The high level of electromagnetic compatibility (EMC) makes it possible to use
advanced digital technology-based functions in electrical substations, without
the need for any particular precautions.
c Sepam 2000’s continuous self-testing sets the device in a predetermined
fail-safe position whenever a failure occurs, thereby preventing random operation.
c Terminals that are individually disconnectable while energized allow easy
maintenance.
c The communication function option can be used for remote setting, remote
metering, remote annunciation and remote control via a two-wire link with a central
computer for centralized control.
c Setting and testing are extremely simple: direct readout of primary current
and voltage and simple testing of the metering function by injection guarantee
the coherency of all settings.
c Each Sepam is designed to meet all the application needs and includes all
the necessary functions ready for use (protection, metering, program logic and
annunciation).
The program logic can be adapted for the usual schemes by simple parameter
setting at the time of commissioning.
This allows optimization of cables and more dependable operation (the schemes
have been qualified and specified to take into account the most frequent needs).
The extended setting ranges provide for the widest variety of cases.
c The disturbance recording function allows up to 12 analog signal and 32 logical
signals to be recorded.
Sepam 2000 standard S36.
Installation in the switchboard is simplified:
c just one device to install, the Sepam 2000 S36 (standard),
c cabling is limited to:
v standard 1 A or 5 A current transformers or linear CSP sensors (Rogowski coil),
v voltage transformers,
v control and annunciation units (open/close push-button...),
v actuators (tripping and closing coils).
Customization
Standard control and monitoring carried out in Sepam’s internal PLC
can be customized.

Metering
Sepam 2000 is a precision instrumentation device.
It gives a direct readout of values, together with
the related units, A, V, W...
All the values needed for operation and used
for commissioning are available locally and in
the control room.
Measurements needed for operation
Currents
Measurement of the current for each of the 3-phases of the circuit.
Peak demand current
Measurement of the greatest average current value in the 3 phases, used to find
the current demand during peak load periods. The average current measurement
is reset to zero periodically (adjustable period: 5, 10, 15, 30 or 60 minutes).
The “clear” button is pressed for zero reset.
Voltage
Measurement of the 3 phase-to-phase voltages of the circuit.
Real / reactive power
Measurement of the real and reactive power, with the sign, in balanced
and unbalanced 3-phase networks.
Peak demand real / reactive power
Measurement of the greatest average real power (and reactive power) value,
to find the power absorbed during peak load periods. The average value is reset
to zero periodically periodically (adjustable period: 5, 10, 15, 30 or 60 minutes).
The “clear” button is pressed for zero reset.
Power factor (p.f.)
Measurement of the p.f. with the sign and type (capacitive or inductive)
of the power conveyed.
Measurements available on the Sepam display unit
and on the TSM 2001 pocket terminal.
Frequency
Measurement of frequency (based on the U21 voltage input).
Real and reactive energy
The alphanumeric display unit shows the 4 accumulated energy values:
c real energy consumed,
c reverse real energy,
c reactive energy consumed,
c reverse reactive energy.
The accumulated energy values are saved in the event of a power failure.
Tripping currents
Measurement of the 3-phase currents and earth current that were stored
at the time that Sepam gave the tripping order. Used to find the fault current
(fault analysis) and assess the level of wear of the breaker
(maintenance assistance). The “clear” button is pressed for zero reset.
Measurements available on the Sepam display unit
and a PC via SFT 2801 software.
True rms current
Measurement of the rms value of phase 1 current up to 4XIn, taking into account:
c fundamental,
c harmonics up to rank 21st.
Disturbance recording
Recording of electrical signals and logical information before and after a fault
recorder triggering order is given.

Protection
Breaker failure (ANSI 50BF-62) F981*
Back up protection in the event that the incoming
breaker fails to operate when a retripping order is
given by the opposite and coupling breakers.
Phase overcurrent (ANSI 50/51) F011 to F014*
Three-phase protection against phase-to-phase
faults. The following types of time delay settings
are available: definite, standard inverse, very inverse
and extremely inverse.
Overvoltage (ANSI 59) F301*
Protection against abnormally high voltage.
The protection checks phase-to-phase voltage U21.
Neutral voltage displacement (ANSI 59N) F391*
Used with a sufficient time delay, detection of residual voltage is characteristic
of voltage transformer fuse melting.
Directional overcurrent (ANSI 67) F521*
Quick, selective detection of upstream faults when several transformer incoming
feeders are used in parallel.
Earth fault (ANSI 50N/51N) F081 to F084*
Earth fault protection. The following types of time
delay settings are available: definite, standard
inverse, very inverse and extremely inverse.
Earth fault current may be detected by:
c three phase current transformers,
c a current transformer (1 A, 5 A) combined
with a CSH30 interposing ring CT.
Directional earth fault (ANSI 67N) F501*
This function has several uses:
c highly sensitive earth fault protection for in coming feeders supplied with power
by a long cable (high capacitive current),
c highly sensitive earth fault protection for long incomers characterized by high
capacitive current.
Undervoltage (ANSI 27) F321, F341, F361*
This function checks for undervoltage in each
of the phase-to-phase voltages measured.
Current sensor sizing
*Fxxx function identification for protection setting using
the pocket terminal.

The current sensors should be such that they will not be saturated by the current
values which they are required to measure (at least 5 In):
c for definite time functions (DT): 1.5 times the setting current,
c for IDMT functions (SIT, VIT, EIT and UIT): 1.5 times the greatest working value
in the curve.

Control and monitoring
Open / close control
Used to control breaking of devices equipped
with different types of opening and closing coils:
c circuit breaker with shunt-trip or undervoltage
release coil.
c parameter setting via the TSM 2001 pocket terminal
allows the logic to be adapted to suit the equipment
being used (by default, the logic is adapted for control
of a circuit breaker with a shunt-trip coil).
The opening order (via input I13) differs according to
the programmed type of control :
c normally open contact for shunt trip coil (circuit
breaker or contactor with latched order control),
c normally closed contact for undervoltage release
coil (circuit breaker).
Lockout relay (ANSI 86)
Stores tripping orders (lockout) and requires user
action to be put back into operation (reset).
Inhibit closing (ANSI 69)
Inhibits the closing of the circuit breaker
or the contactor according to operating conditions.
Annunciation (ANSI 30)
Keeps the user informed by the display of messages.
CB control monitoring:
trip circuit, discrepancy (ANSI 74)
Detects trip circuit faults (shunt-trip coil). The function
can only be used if the Sepam and trip circuit auxiliary
power sources have the same voltage rating.
If the equipment contains an undervoltage release
coil only, the trip circuit is not supervised since
it is fail-safe.
This function can also detect position information
discrepancies (neither open nor closed
or simultaneously open and closed) in the different
control schemes.
This function can also detect all control open and
closed not executed.
The connection scheme of inputs I1, I2 and trip
output O1 on the ESB board must be complied
with (see logic input (output connection schemes).
8
Tripping of upstream (HV) and couling breakers
In the event of the failure of an incomer breaker to trip, it trips the upstream (HV)
and coupling breakers. May also be used to trip the upstream (HV) breaker in the
event of directional protection tripping.
External protection tripping
Allows the breaker to be tripped by a protection outside the Sepam.
External disturbance recording triggering
Used to start up external disturbance recording whenever an overcurrent
or earth fault is detected.
Sepam disturbance recording triggering
Triggers recording of electrical signals and logical states by:
c voluntary local or remote action,
c instantaneous overcurrent and earth fault and directional protections,
c protection tripping order.
Power supply monitoring
Detects all losses of auxiliary power supply or Sepam failures (watchdog).
Detection of plugged connectors (DPC) (ANSI 74)
Indication on the display unit that one or more connectors are not plugged in
(the DPC connections must be made: see connection schemes).
Phase and earth fault trip counter (1)
Counts the number of operation for which breaking performances are required,
in order to facilitate equipment maintenance.
Logic discrimination (SSL) (ANSI 68)
Enables quick and selective tripping of the phase overcurrent and earth fault
protection relays, whether definite time (DT) or IDMT (standard inverse SIT,
very inverse VIT, extremely inverse EIT, ultra inverse UIT).
The function triggers the transmission of a blocking input (BI) signal whenever one
of the protection settings is exceeded.
The transmission of a blocking input may be used by the Sepam Logic Discrimination
function for substation, overhead, underground or busbar coupling applications.
Operation counter (1)
Counts the number of closing operations performed by the breaking device,
in order to facilitate equipment maintenance.
(1)
the counters are read on the pocket terminal.
