GENERATOR PROTECTION RELAY
GENERATOR PROTECTION RELAY (MG30 & MG30-I); These are Multifunction Microprocessor Relay for
protection of medium/ large synchronous generators. The relay measures the RMS of three-phase currents and voltages and
computes the positive and negative sequence components of the Current system. A separate input is dedicated to the
measurement of the Neutral-to-Ground voltage and its harmonic components used for a complete Stator Ground Fault
protection. MG30 incorporates 5 output relays expandable up to 16 with the additional module REX-8.
Features;
 Voltage-controlled over-current protection.
 Thermal image element with pre-alarm level.
 Reverse power protection.
 Loss of Field protection.
 PT s' fuse failure protection
 Modbus Communication Protocol
 Breaker Failure protection
 Inadvertent C/B closure protection
 Blocking Output and Blocking Input for pilot wire selectivity coordination.
