Design and Implementation of Digital Leakage Current Circuit Breaker with Overcurrent Protection

Abstract

One of the main issues is how to protect people and electrical equipment from the dangers of electricity. Common defective current types that harm both consumers and electrical equipment include leakage, overload, and short-circuit currents. Both of these faults have the potential to start fires or electrocute people. The employment of traditional electrical protection devices is common in electrical systems to mitigate the impact of defective currents. Many conventional electrical protection devices lack accurate fault detection techniques and quick trip times. In this work, we introduce a digital leakage current circuit breaker with overcurrent protection and a digital device for electrical fault prevention for users and equipment. The goal of this project is to use a microcontroller to computerize the fault detection procedure of a traditional breaker. This fully automated device's settings can be changed according to user needs while keeping flexibility and safety. The experimental results show that the system was able to detect errors in the electrical current and stop them while clarifying the type of error (leakage or overload currents).
