Working Principle
The protection relay continuously monitors electrical parameters through current and voltage transformers. When abnormal conditions are detected (overcurrent, short-circuit, earth fault), the relay calculates the fault characteristics and triggers appropriate protective actions, such as tripping circuit breakers. The modular control functions enable process optimization through feedback loops and adaptive algorithms.
