Abstract

Many electrical faults such as short circuit or overcurrent and earth fault that occur are momentary in nature. Because of that the breaker has to be reset manually or by remote control. The circuit breaker has no means of knowing whether the faults still exist. The automatic reclosing system is a system that can able to detect either the fault (overcurrent or short circuit and earth fault) in the system are may still exist or not. Once the fault is cleared, it will automatically switch on back the breaker/switch. It is different from other recloser that been used because this system is applied to single phase system which are one of common system in used. In this project, an attempt will be made to incorporate smart circuit into the circuit breaker system. This circuit needs to test the system for any fault that may still exist. This circuit can be performed by application of an electronic controt circuit (using digital technology). This circuit consists of the electronic circuit breaker, the application circuit which function to retest the system, the conditioning circuit and also the sensor of fault. The advantages of this system are reducing in consumer equipment down time and maintenance time.
