Design and Control Motorized Circuit Breaker in Electrical Distribution Panel

Abstract

A circuit breaker is the main part of the distribution panel that needs to control for safe operation. It is important for protection and switching in the power system. Automatic control of circuit breakers using motorized can be realized by the microcontroller scheme. In this paper, a microcontroller equipped with wifi and an internet connection is used to control and monitoring the circuit breaker. The design of the circuit is proposed and experiment result is obtained. The response time is about 1 second to complete the process to control the circuit breaker. Error in monitoring application is about 3% for voltage measurement and 3.5% for current measurement. The proposed circuit system showed good and reliable control and monitoring of circuit breakers in every condition include of closing, opening, and monitoring.
