Main Characteristics

The Sepam™ Series 80 offers these features

a)protects closed ring networks or networks with parallel mains by means of directional protection and zone selective interlocking

 b) directional ground fault protection for impedance-grounded and effectively ungrounded or compensated neutral systems (designed to compensate for system capacitance using a tuned inductor in the neutral. This is not common inNorth Americ

1. c) complete protection of transformers and machine-transformer unstable, sensitive differential protection with neural network restraint

 linked to all necessary backup protection functions*

1. :d) complete protection of motors and generators

 against internal faults*

- stable, sensitive machine differential protection, with starting and instrument transformer loss restraint

- field loss, stator ground fault

 against network and process faults: pole slip, speed control, inadvertent energization*

e)sync-check between two networks before closing tie breaker

1. f) measurement of harmonic distortion, current and voltage, to assess network power quality

1. g) 42 inputs / 23 outputs for comprehensive equipment control

1. h) mimic-based UMI for local switchgear control

1. i) SFT2841 parameter setting and operating software, a simple and complete tool that is indispensable for all Sepam™ users

 assisted preparation of parameter and protection settings*

 complete information during commissioning*

remote equipment management and diagnostics during operation*

j)logic equation editor built into the SFT2841 software to adapt the predefined control functions

k)optional SFT2885 programming software (Logipam), to program specific control and monitoring functions

1. l) two communication ports to integrate Sepam™ in two different networks or redundant architectures

1. m) removable memory cartridge to get equipment in operation again quickly after the replacement of a faulty base unit

 n) battery backup to save historical and disturbance recording data
