All the electrical equipment’s need to be protected from hazards. The goal of Intelligent Circuit breaker controller is to protect and control the power distribution line by both remotely and manually during interruption or faults. The intelligent circuit breaker is mainly used in electrical equipment’s against over load, Single phase grounding fault and short circuit. It will be installed in the distribution stations and operated with password both for remote and manual access. Fault location is identified by calculating the line impedance. It will also detect the open circuit fault. The intelligent circuit breaker is designed and tested. PIC16F877A microcontroller is used for implementing the proposed intelligent circuit breaker.
