ANSI solid state, undervoltage relay Type 27G

Solid state, 27G 180 Hz, third harmonic undervoltage relay, designed for distribution systems

The type 27G relay is specifically designed to protect generators against internal ground faults at or near the neutral end of generator windings. This relay is designed to be sensitive to third harmonic voltages only. It is usually used in conjunction with the Type 59G, ground voltage relay, to provide 100% generator stator ground fault protection.
