Introduction
Presentation
The Sepam™ range of protection relays is
designed for operating machines, the
electrical distribution networks of industrial
installations, and utility substations at all
levels of voltage. The Sepam™ family
includes:
b Sepam™ Series 20
b Sepam™ Series 40
b Sepam™ Series 80
to cover all needs, from the simplest to the
most complete.
Sepam™ Series 80: Intelligent Solutions for
Custom Applications
Specially designed for demanding customers on large industrial sites, Sepam™
Series 80 provides proven solutions for electrical distribution and machine protection
Main Characteristics
The Sepam™ Series 80 offers these features:
b protects closed ring networks or networks with parallel mains by means of
directional protection and logic discrimination
b directional ground fault protection for impedance-grounded and isolated or
compensated neutral systems
b complete protection of transformers and machine-transformer units
v stable, sensitive differential protection with neural network restraint
v linked to all necessary backup protection functions
b complete protection of motors and generators
v against internal faults:
- stable, sensitive machine differential protection, with starting and sensor
loss restraint
- field loss, stator ground fault
v against network and process faults: pole slip, speed control, inadvertent
energization
b sync-check between two networks before tie breaker
b measurement of harmonic distortion, current and voltage, to assess network
power quality
b 42 inputs / 23 outputs for comprehensive equipment control
b mimic-based UMI for local switchgear control
b SFT2841 parameter setting and operating software, a simple and complete tool
that is indispensable for all Sepam™ users:
v assisted preparation of parameter and protection settings
v complete information during commissioning
v remote equipment management and diagnostics during operation
b logic equation editor built into the SFT2841 software to adapt the predefined
control functions
b optional SFT2885 programming software (Logipam), to program specific control
and monitoring functions
b two communication ports to integrate Sepam™ in two different networks or
redundant architectures
b removable memory cartridge to get equipment in operation again quickly after
the replacement of a faulty base unit
b battery backup to save historical and disturbance recording data
