MG30

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.

Salient Features:

• Voltage-controlled overcurrent protection
• Thermal image element with prealarm 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
