Sepam series 80

Sepam series 80 offers intelligent solutions for complete applications. Specially designed for demanding
customers on large industrial sites.
Sepam series 80 provides proven solutions for electrical distribution and machine protection:
• protection of closed ring networks or networks with parallel incomers by directional protection and
logic discrimination.
• directional earth fault protection for impedance-earthed and isolated or compensated neutral systems.
• complete protection of transformers and machine-transformer units
– stable, sensitive differential protection with neural network restraint
– linked to all necessary backup protection functions
• complete protection of motors and generators against internal faults:
– stable, sensitive machine differential protection, with starting and sensor loss restraint
– field loss, stator earth fault, etc.
– against network and process faults: pole slip, speed control, inadvertent energization, etc.
• measurement of harmonic distortion, current and voltage, to assess network power quality
• 42 inputs / 23 outputs for comprehensive equipment control
• logic equation editor for specific control functions
• 2 Modbus communication ports to integrate Sepam in 2 different networks or redundant architectures
• removable memory cartridge to get equipment in operation again quickly after any replacement
• battery backup to save historical and disturbance recording data.
