Development of Intelligent Automatic Electronic MCB and ELCB Using Fault Diagnosis Technique

Protection system and continuous power supply are important for residential and commercial areas. To ensure enhanced protection, automatically operated intelligent miniature circuit breaker (MCB) and earth leakage circuit breaker (ELCB) is developed using advanced current measurement and fault diagnosis technique. Whenever short circuit or earth fault occurs the system will trip and power supply is if it is temporary fault system will restore power supply using advanced fault diagnosis technique and if it is permanent fault it will remain off. Thus, the aim of this paper is to develop an intelligent protection system to overcome problems of electromechanical circuit breakers. The automatic system is able to detect, diagnose, interrupt and reclose the circuit breaker in order to ensure power supply continuity along with safety.
