Protecting your installation:
dependability, optimization and profitability
Electrical network
protection is an
objective of prime
importance to all
installation managers
in the Power
distribution utilities.
The protection plan for electrical installations and networks must:
c guarantee the safety of people and property
c improve continuity of service
c contribute to the performance of your electrical installation
Protection units enable the operator to:
c measure electrical values
c manage data according to his requirements
c monitor and control power equipment
Furthermore, digital protection units are integrated
in centralized monitoring and control systems enabling:
c optimized installation telecontrol
c maintenance management
Protection units are adaptable to developments in the electrical network
and in particular the upgrading of existing installations.
The protection units must be easy to choose, install and operate.
Activated when incidents occur on the electrical network or in the
installations, the dependability and availability of these units must be
tested and proven in the field.

Sepam concept
Mastery of digital techniques
As a result of the success of the first Sepam unit, Merlin Gerin developed
a new range: Sepam 1000+ and Sepam 2000.This range is more comprehensive,
more effective and fully appropriate for the control of electrical substations in public
and industrial distribution systems. All protection and control devices must:
c supply optimal service under the best security and availability conditions,
c ensure dependable operation in the highly disturbed electrical substation
environment.
Electromagnetic compatibility testing is performed
in an anechoic chamber.
To achieve these objectives, the development of this new range called
for substantial implementation of expertise and enhanced investigations
in the following main areas:
c electrical phenomena, transient operation,
c signal processing,
c protection algorithms,
c electromagnetic compatibility (EMC),
c dependability, reliability,
c communication networks.
During the design phase, dependability studies (FMECA (1)) were carried out
to determine the hardware and software architectures, considerably improving
availability and operating security.
All the studies were performed in accordance with a stringent quality plan.
A large number of qualification tests were performed, in a dedicated protection
testing laboratory (Kirchhoff laboratory).
The protection functions are tested in the laboratory by simulating the phenomena
(EMTP (2)) as they appear in electrical networks.
Major advantages
The use of digital techniques provides protection and control devices with major
advantages:
Kirchhoff protection testing laboratory.
Availability
The use of extensive self-testing and self-diagnosis procedures allows wide-range
monitoring of the device.
The user is continuously informed of Sepam’s operating condition.
He can therefore take immediate and efficient action in the event of a failure.
The risk of running an installation with faulty protection is substantially lowered.
Periodic testing is no longer essential.
Global cost reduction
The integration in a Sepam of all the functions needed for the protection and
control of a system offers substantial advantages such as more rational operation,
optimized performance and better service for a reduced overall cost.
Reduction in the cost of:
c design: by the choice of units that are ready to use, without requiring detailed
engineering work,
c installation: by the integration of auxiliary relays, measuring instruments
and annunciation devices,
c commissioning: by simple installation and testing,
c operation: by remote control and improved access to more complete information,
c maintenance: by the reduction of preventive maintenance.
Dependability
Extensive dependability and reliability calculations have been carried out
on Sepam. They show that the failure rate, and therefore the risk of misoperation,
is minimized with an integrated Sepam type solution.
Simplicity
Sepam requires only simple parameter setting (calibration of the current
and voltage transformers, and general information on the network).

Flexibility
The flexibility of Sepam 2000’s built-in PLC makes it suitable for all possible
control logic schemes.
Sepam range
A complete range
All applications
The Sepam range is a set of protection and control units which have the capacity
to fullfil all types of applications:
c substations,
c busbars,
c transformers,
c motors,
c capacitors,
c generators,
c measure and control.
Each Sepam is an optimized solution in terms of functions, performance and price.
A complete range:
Sepam 100, Sepam 1000+ and Sepam 2000.
All functions
Each Sepam includes all the protection, metering, control, monitoring
and annunciation functions required for its assigned application.
The functions have very wide setting ranges, all types of curves, and can therefore
fit into any protection system.
The choice of functions offered in each Sepam is the result of the engineering,
experience and expertise of Merlin Gerin specialists who are confronted daily with
the challenge of developing electrical equipment projects.
In addition, the so-called “logic discrimination” function makes it possible to
further lower the tripping time when a fault occurs, whatever the time discrimination
intervals and the type of curve (definite time or IDMT).
This principle makes it possible to incorporate economical busbar protection,
or to set a shorter protection time delay upstream than downstream,
and still maintain tripping discrimination.
It means that Sepam can meet the protection and control needs of low voltage
networks and high voltage networks up to 220 kV as efficiently as required.
Industrial range
The design of all the types of Sepam for each application is based
on two hardware units: Sepam 1000+ series and Sepam 2000 series.
The hardware manufacturing process is ISO9001 certified and includes a burn-in
cycle. Sepam’s robust and its outstanding electromagnetic compatibility (EMC) allow
it to be used in highly disturbed environments without requiring any particular
precautions.

Sepam 2000
Presentation
Sepam 2000 is focused on performance.
It can be used for the most demanding applications.
Sepam 2000 has a large control and monitoring capacity, provided by its built-in
PLC and interface for communication with a centralized control system.
The built-in PLC considerably cuts down on the use of auxiliary relays and the
associated wiring.
Each Sepam 2000 is supplied with its standard control and annunciation program,
which allows it to be used without any additional engineering work or programming.
The available data as well as Sepam 2000’s remote control capacity enable it to be
integrated in an energy management system. Sepam 2000 reports to the control
room, so the user is immediately informed of any situation. Having this information
at his disposal, he can take the appropriate measures without leaving the control
room.
Standard (S36) Sepam 2000
and compact (S26) Sepam 2000.
Each Sepam 2000 is designed to meet all the application needs and includes
all the necessary functions, ready for use.
Simply choose the appropriate Sepam 2000 from the selection tables showing
the functions available for each application (1) :
c substations,
c busbars,
c transformers,
c motors,
c capacitors,
c generators.
Example :
An incomer in a substation with multiple supply sources, in a high impedance
earthed system, should be equipped with:
c definite time or IDMT phase overcurrent and earth fault protection,
c directional overcurrent and, sometimes, directional earth fault protection
for discrimination between parallel incomers.
c an undervoltage relay to control supply source changeover.
c all the measurements and accumulated energy readings needed to operate
the substation. For this application, the S03 type Sepam 2000 could be chosen,
including the standard control and monitoring functions, such as trip circuit
supervision and logic discrimination.
Standard Sepam 2000 is delivered with its connectors.

Sepam range
Control logic and annunciation
Each type of Sepam 2000 is equiped with a built-in PLC with at least 10 logic
inputs and 6 logic outputs (which can be extended to 26 inputs and 14 outputs).
This flexibility is provided for standard network management automation functions
such as logic discrimination, reclosing, load shedding, etc.
Customized process control programs may also be developed on Sepam
(see “for customized applications” document).
Simple setting with the TSM 2001 pocket terminal.
Description
Sepam 2000 replaces measuring instruments such
as ammeters, voltmeters, wattmeters,
energy meters, etc.
It displays alarm and operating messages related to
the protection functions and control logic systems,
thereby eliminating the many indicating lamps found
on previous installations.
The front face includes:
c a lighted alphanumerical display, legible from a
distance of several meters,
c keys to select the measurement to be displayed
and to acknowledge messages. As a security feature,
these keys do not give access to the protection
settings,
c 3 lights:
v “trip” (tripping by the protective relay),
v “circuit breaker open”,
v “circuit breaker closed”,
c a green light indicating the presence
of “auxiliary power supply”,
c a red light signalling malfunctions and relay fail-safe
position (watchdog),
c a door for access to:
v to the serial connection inlet,
v the cartridge slot.
The cartridge contains the different programs required
for Sepam 2000 operation.
Operation
Sepam 2000 is simple to consult and set thanks to the serial link on the front of the
device.
The settings may be made on the front panel (serial link):
- one by one, using the TSM2001 pocket terminal, or the SFT2801 PC software
program,
- all at once using the SFT2821 PC software program (downloading),
The TSM 2001 pocket terminal is equiped with a keyboard, a 4-line display
(20-character per line) and a menu system.
It is easy to read measurements, enter settings, modify operating conditions
and review maintenance information such as “fault current”, “number of c.b.
operations”, etc.
Access to the protection function settings is protected by a password.
Sepam 2000 stores the parameters and the settings in its non volatile memory.
In the event of an auxiliary power supply failure, they are saved and retrieved
as soon as the power is restored.
Disturbance recording
Sepam 2000 has a high performing disturbance recording function. It is used to
record analog signals (current/voltage) and logic states during a time interval which
includes the disturbance. Sepam 2000 also has a graphical wave form recovery
software package for the analysis and use of the data (SFT 2826).
Communication
Sepam 2000 offers the option of a high performing communication module.
(Jbus/Modbus or other) * for connection to a remote control and monitoring device.
This option provides:
c measurement of electrical variables
c annunciation,
c switchgear control
c reading and modification of settings
c network diagnosis by :
v event logging
v graphical wave form display.
Installation and connection
Sepam 2000 is delivered with its connectors.
The connectors are individually disconnectable
screw-on terminals.
All types of Sepam can be installed by making
a simple rectangular cut-out in the mounting support.
Some types of Sepam 2000 also come in a compact
version (S26).

The figures in the columns represent the number of similar protection devices.
For example, for phase overcurrent protection, “4” means: 4 separate overcurrent protection devices.
(1)
inter-tripping: this is related to neutral voltage displacement, tank earth leakage, neutral protection functions and Buchholz tripping, gas detector tripping, pressure
detector functions.
(2)
for transformers needing temperature captors, please contact us. for differential protection, please see Sepam D01, for restrictive earth fault protection, please see
Sepam 100 LD.
(3)
types of Sepam with tank earth leakage and neutral can’t be connected to CSP sensors.
(4)
the tank earth leakage and restricted earth fault protections are exclusive. The choice is made parameter setting. See other connection schemes for restricted
earth fault.
* available function with 2 sets of sensors.

customization
In addition to the protection and metering functions, Sepam 2000 also includes
control logic and annunciation.
This standard control logic may be adapted to most usuals schemes by a simple
parametring at commissioning stage.
This enables optimized cabling and more dependable operation.
(Diagrams are specified to take into account the most frequent needs).
In order to offer greater flexibility to adapt to your installations, functions can be
modified and new control and annunciation functions can be added by
programming in an electrican’s language (Logipam (1)).
Programming can be done on site.

Sepam 100
Presentation
Sepam 100 is a series of modules which fit the Sepam range.
These modules can be installed on their own or combined with Sepam 1000+
or Sepam 2000.
Sepam 100 includes:
c on front panel: orders, settings and informations,
c on rear panel: connectors.
The Sepam 100 series includes several types:
c Sepam 100 LA provides DT phase and residual current protection without
requiring an auxiliary power supply. Combined with Sepam 1000+ or 2000,
this module provides “reflex” protection, operating in redundancy, in the event
of a failure in the main protection chain (auxiliary power suply, tripping, etc).
c Sepam 100 RT processes the information received from the transformer
thermostat and Buchholz contacts. It provides annunciation, tripping and circuit
breaker lockout (this information is stored in the event of an auxiliary power
failure), trip circuit supervision...,
c Sepam 100 LD provides high impedance differential protection,
c Sepam 100 MI modules are used for control and annunciation of the protection
of circuit breaker and isolating switches.
(a large number of mimic diagram schemes are available).
Most frequently used complementary modules:
Sepam100 LA, Sepam100 RT.

Sensors
Standard current sensors
Sepam is adapted for all types of phase and residual current sensors:
standard 1A or 5A with rated currents from 10A to 6.25 kA.
CSP current sensors
The CSP type current sensors, designed by Merlin Gerin, operate according
to the Rogowski coil principle. The CSP sensors incorporate a special coiling
technique and have no magnetic core. This provides them with the following
properties:
c no saturation: linear response,
c no hysterisis or remanence: transient phenomena are accurately reproduced,
without any wave form deformation.
CSP type current sensors are used with Sepam 2000.
The CSP-Sepam 2000 assembly forms a coherent protection and metering chain,
which results in the following advantages: simplification of current sensor
specifications,(choice among only 4 sensors),
CSP sensor.

CSH core balance CTs
The CSH 120 and CSH 200 core balance CTs, designed by Merlin Gerin,
provide more sensitive protection by direct metering of earth fault current.
The only difference between the two core balance CTs is their diameter.
Both can be connected to either of Sepam’s input ratings: 2 A or 30 A.
