Introduction
Induction motors are generally used as a part of the industry, their hardness and speed control are paid for flexibility. Maner attracted the issue of induction motor protection Many researchers The goal of this project is to protect the three phase induction motor. There are various techniques for detecting Sameer's fault, stator-flot checking, microcontroller-based protection systems and programmable controller (PLC) based protection systems to use the protection of autofitial neutral network for fault detection and induction motor. In this work, the technology used to be this will be the complete control of the microcontroller-based security system circuit Will Take Motor and it will protect the motor, for example, over voltage and under-voltage and circuit motor will switch under under-safety conditions. This protects the extra induction motor The single fault which is a major fault circuit is completely controlled by the microcontroller and the microcontroller will constantly monitor the voltage. Three phases and if the voltage becomes abnormal, then IT will close the motor until they are normal. At the same time, the support of the current transformer which understands the present and if the ITXSD sets a certain level then the comparator sends it Sign the microcontroller to stop the motor. All the conditions are shown on the LCD display. In these papers we are using 8 bit microcontroller AT89C52. IT has a 40 pin microcontroller microprocessor capable of switching in the safety of the induction motor with the ability to make the empty time, every time the monitors phase of the motor Also known through every motoring activity, the LCD display protects the motor from single-phasing as the cost of management is low Learn about the same fault mode An induction motor drive system improves the behavior of system protection and control Is critical from angle
