Technology in context.
ERLPhase provides protection relays and disturbance recorders for power systems. These serve related but distinct protection and investigation requirements.
Protection matched to the apparatus
Relay families address line, transformer, bus, feeder and motor protection. The protection scheme determines the measurement inputs, logic and communication requirements.
Retain the evidence around a disturbance
TESLA recording systems capture power-system events for analysis. Recording and record-management tools help engineers investigate disturbances and review protection behaviour.
