The Sepam™ Series 80 offers these features:
- protects closed ring networks or networks with parallel mains by means of directional protection and zone selective interlocking
- 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 in North America).
- 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
- complete protection of motors and generators v against internal faults: – stable, sensitive machine differential protection, with starting and instrument transformer loss restraint – field loss, stator ground fault v against network and process faults: pole slip, speed control, inadvertent energization
- sync-check between two networks before closing tie breaker
- measurement of harmonic distortion, current and voltage, to assess network power quality
- 42 inputs / 23 outputs for comprehee equipment control
- mimic-based UMI for local switchgear control nsiv
- 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
- logic equation editor built into the SFT2841 software to adapt the predefined control functions
- optional SFT2885 programming software (Logipam), to program specific control and monitoring functions
- two communication ports to integrate Sepam™ in two different networks or redundant architectures
- removable memory cartridge to get equipment in operation again quickly after the replacement of a faulty base unit
- battery backup to save historical and disturbance recording data
