Transformer Services - GE Grid Solutions transformers are critical for ensuring a sustainable supply of power to prevent outages. With the loss of insulation being irrecoverable, transformer failure risk can be minimized only if oil quality is maintained, moisture is controlled, temperatures are managed, incipient faults are detected and corrected, and an overhaul is conducted at midlife.
Circuit breaker - Wikipedia circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit.Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume ...
