Abstract

Protection of the power system plays an important role in the safety of electrical appliances and the user at residential or building. Earth leaked circuit breaker (ELCB) is a safety circuit breaker installed on high-earth electrical wiring systems to prevent electrical shock. Most electrical wiring has a high earth impedance due to the use of earth rods in the TT grounding system or dry soil conditions. This such of wiring is dangerous and exposed to risks in case of an electric current flowing due to leakage from live wires to ground wires. So ELCB should always be in good condition to carry out the task of protecting the power system. This project is developing to prevent users from being exposed to electricity and to simplify users to switch on the ELCB when the ELCB tripped due to leakage to ground or short circuit by sending SMS to the GSM. Arduino UNO will be used in this project to automatically control ELCB by programming it. When the short circuit or overcurrent occurred ELCB will trip and Arduino will send a signal to Global System for Mobile (GSM) and GSM will send the SMS to the user. After the user replies the SMS Arduino will process and send instructions to the motor to switch on the ELCB by pulling the trigger. This system provides convenient way for resident especially during nobody at home.
