- Thermal & Temperature Protection: Real‑time stator thermal modeling; optional RTD monitoring for winding, bearing, and ambient temperatures.
- Over/Under Excitation Protection: Protects generators from over‑excitation and under‑excitation conditions.
- Voltage & Frequency Protection: Overvoltage (59), undervoltage (27), overfrequency (81O), underfrequency (81U), and rate‑of‑change‑of‑frequency (ROCOF) protection.
- Motor‑Specific Protection: Stall protection, cumulative start‑up counter, phase discontinuity, and unbalanced load protection for motor start‑up and operation.
- Generator Motoring Protection: Detects reverse power flow to prevent generator motoring damage.
- Under‑Impedance Protection: Protects against stator winding faults and abnormal operating conditions.
- Breaker Failure Protection (CBFP): Initiates backup tripping for main breaker fault clearance failure.
