G60-G03-HCH-F8L-H6C-M8N-P6C-U6C-W6C-High-end Digital Integrated Generator Protection Relay

Protection Function Parameters

Differential protection: Stator differential protection (87S), rotor earth fault protection (GPM-F module optional), 100% stator earth fault protection (GPM-S low-frequency injection module optional)

Abnormal operating condition protection: Loss-of-excitation protection, overexcitation V/Hz protection, reverse power protection, negative sequence overcurrent protection, over/under frequency protection, overvoltage/undervoltage protection, out-of-step blocking protection, circuit breaker failure protection (50BF)

Operating speed: Short-circuit fault operating time <30 ms; general protection operates within 2~6 cycles; timing accuracy ±3% or 20 ms (whichever is larger)
