Sepam 1000+ series 20
Suitable for
common applications
, Sepam 1000+ series 20 offers
simple
solutions
based on
current
or
voltage metering
.
The
Sepam 1000+
family of protection and
metering units is designed for the operation
of machines and electrical distribution
networks of industrial installations and utility
substations for all levels of voltage.
It consists of
complete, simple and
reliable solutions
, suited to the following
applications:
The
Sepam 1000+ series 20 S20, T20 and M20 current units
cover applications
such as the following:
protection of substation incomers and feeders
against phase-to-phase and
phase-to-earth short-circuits
16 IDMT tripping curves
adjustable timer hold to detect recurrent faults
switching of groups of setting to adapt to changes in the network configuration
protection of overhead lines
with reclosers
protection of transformers
against overloads, with ambient temperature-
compensated RMS thermal overload protection with 2 groups of settings for different
ventilation operating rates
protection of motors
against overloads, with ambient temperature-compensated RMS thermal overload
protection with a cold tripping curve that can be adjusted to fit motor characteristics
against internal faults and load-related faults
with motor starting condition monitoring and machine operation assistance.
protection of
substations
(
incomers
and
feeders
)
protection of
transformers
protection of
motors
protection of
busbars
.
The
Sepam 1000+ series 20 B21 and B22 voltage units
are suitable for the
following situations:
monitoring of network voltage and frequency
loss of mains detection by rate of change of frequency protection for installations
with local power generation.
Sepam 1000+ series 40
Sepam 1000+ series 40
, with its
current and voltage metering
capabilities,
offers
high-performing solutions
for
more demanding applications
.
Sepam 1000+ series 40
units perform the following functions in addition to those
performed by Sepam 1000+ series 20:
protection of networks with parallel incomers by directional protection
directional earth fault protection suitable for all earthing systems, impedant,
isolated or compensated neutral
all the necessary electrical measurements: phase and residual current, phase-to-
neutral, phase-to-phase and residual voltage, frequency, power and energy, …
comprehensive network diagnosis assistance: 20 seconds of disturbance
recording, detailed history of the last 200 alarms, storage of contexts of the last
5trips
adaptation of control functions by a logical equation editor
customization of alarm messages to fit each application, and/or in the user's
language.

More simplicity
Simple to install
no constraints for integration in cubicles due to the compact size of the base units
and remote installation of optional modules
universal auxiliary power supply.
Simple to commission
all the functions are ready to use
user-friendly, powerful PC setting software to utilize all the possibilities offered by
Sepam 1000+.
Simple to operate
With the advanced UMI, all local operations are made easier by a clear, complete
presentation of all the required information in your language.
Simple to maintain
digital unit self-diagnosis and watchdog
switchgear diagnosis assistance functions to assess equipment condition and
schedule preventive maintenance operations:
cumulative breaking current
breaking device operating and charging time.
More communication
Modbus communication
All the data needed for centralized management of your electrical network are
available with the communication option based on the open, international Modbus
protocol:
measurement and diagnosis values
remote indication and time-tagging of events
remote control of the installation
remote setting of protection functions
reading of disturbance recording files.
Ethernet connection and Webserver
Sepam 1000+ can be connected to an Ethernet broadband network by Ethernet/
Modbus communication gateways.
With these gateways :
Sepam 1000+ can be integrated in any automation and supervisory system based
on Modbus / TCP/IP multi-master protocol
Web pages presenting information provided by Sepam may be consulted via an
Internet/Intranet browser.
PowerLogic System
Sepam 1000+ is a component of PowerLogic System and may naturally be
associated with SMS centralized industrial and commercial electrical network
management software.

More modularity
Sepam 1000+ is available with 2 User Machine Interface (UMI) levels:
advanced UMI
, with keypad and graphic LCD display
to provide all the data required for local operation of the installation:
measurements, diagnosis information, alarms, etc.
to set Sepam 1000+ parameters and protection functions
to be understood by all, the screens can be displayed in the user’s language.
The advanced UMI may be part of the base unit or installed as a remote unit in the
most convenient location for the user.
basic UMI
, with signal lamps
no need for local operation
for remotely operated installations.
In order to adapt to as many situations as possible and allow for subsequent
upgrading of the installation, Sepam 1000+ may be functionally enhanced at
any time by the addition of optional modules:
logic input/output module with parameterizable program logic
communication module
temperature sensor module
analog output module.
