Implementation of microcontroller based fault detection and protection system for DC motor

Abstract

The acute aim of this paper is to identify the nascent faults that may cause due to various reasons like over current/voltage, under voltage, high temperature, overload, and single phasing and to protect the motor from such faults. These type of faults mainly occur due to variation of parameters i.e. voltage, current, and temperature. Due to this fault, the motor winding gets heated which causes insulation failure, thus the life of the motor reduces. This project uses AT89S51 microcontroller for detection of electrical faults. The same microcontroller was developed by Intel and based on 8-bit microcontroller family. The circuit was designed successfully in Proteus simulation software as well as in real time environment and various testing conditions was applied to check the system robustness. The improved performance of the microcontroller and associate system network is established against system constraints through its efficient mechanism.
