The G60 Generator Management Relay, part of the UR family of protective relays, is a microprocessor-based relay intended for the protection of AC generators. It may be used on any size of generator driven by steam, gas and hydraulic turbine. Protection functions include stator differential, 3rd harmonic stator ground differential and 3rd harmonic neutral undervoltage for 100% stator ground differential protection, sensitive directional power for low forward power and reverse power protection, loss of excitation, inadvertent energization, overexcitation, current unbalance, out-of-step, and a whole suite of under- and overvoltage, and overcurrent functions.
