Core Protection Functions (ANSI Standard)
1. Current Class Protection
Phase-to-phase time-limited / reverse-time overcurrent (51P), instantaneous overcurrent (50P)
Grounding, sensitive grounding reverse-time / instantaneous protection (51N/50N)
Negative-sequence overcurrent protection (46), zero-sequence direction overcurrent
Overload alarm, thermal overload protection (49), CT disconnection detection
2. Voltage & Frequency Class Protection
Overvoltage / undervoltage (59/27), zero-sequence overvoltage protection
High frequency / low frequency, frequency change rate ROCOF low-frequency load shedding (81O/U)
Loss of voltage backup auto-switching, synchronous check / check for no voltage for closing (25)
3. Auxiliary Protection and Control Logic
Breaker failure protection, three-phase one-time reclosing (79)
Reverse power, direction power protection (32)
PT disconnection alarm, fault recording, 1ms precision SOE event sequence recording
Local remote control closing and opening, anti-misoperation locking, breaker wear monitoring (I²t) GE Vernova

Hardware I/O Configuration
Analog Input
Three-phase current (1A/5A CT selectable), three-phase voltage (100V PT), zero-sequence current, zero-sequence voltage
Switching Quantity DI: 16-pair passive switch input (circuit breaker position, disconnect switch, energy storage, local/far control, protection setting)
Switching Quantity DO: 12-pair relay output (trip, close, alarm, signal upload)
High-precision measurement: active power / reactive power, electricity consumption, power factor, harmonic measurement

Communication Interfaces (BF Dual Communication Configuration)
