Design and Implementation a New Real Time Overcurrent Relay Based on Arduino

Abstract

Abstract This paper presents the new design and implementation of single phase overcurrent protection relay based on an Arduino NANO.. The relay is an electromagnetic switch which operated depending upon the input signal that can turn it (ON/OFF) when the measuring current is greater than of the sitting current. The proposed relay provides greater operating flexibility, high sensitivity, reliability, high speed, simple controller. This relay is designed and tested on the electric system, depending on the use of the controller.The experimental results from the electrical system test emerged efficiency and speed of the response system to protect it from any fault.
