MG30 : For Impedance Grounded (NGR / NGT) Generators

MG30-I : For Solidly Grounded Generators

MG30 / MG30-I is 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.

More features: :

Voltage-controlled overcurrent protection

Thermal image element with prealarm level

Reverse power protection

Loss of Field protection

Modbus Communication Protocol

Breaker Failure protection

Inadvertent C/B closure protection

Blocking Output and Blocking Input for pilot wire selectivity coordination
