Relay Protection and Substation Operation
Relay protection is essential to ensure the stability, reliability, and safety of electrical power systems. Generator protection covers: phase-to-phase short circuits in stator windings, stator ground faults, inter-turn short circuits in stator windings, external short circuits, symmetrical overload, stator overvoltage, single- and double-point grounding in the excitation circuit, and loss of excitation. In HV (High Voltage) and MV (Medium Voltage) substations, relay protection safeguards critical assets such as transformers, circuit breakers, and lines. When it detects abnormal conditions—such as overcurrent, short circuit, or voltage instability—it sends a trip signal to the circuit breaker, isolating the faulted. Apply advanced protection and monitoring with flexible communications to two-, three-, and four-terminal transformers.
