Abstract

This project is developed for the users to operate multi generators with automatic change over. It consists of current and voltage sensors, Microcontroller unit and Power transformers.

The current and voltage sensors senses the status of the generator in working. At any cast, if one generator is not working, the sensor sends signal to the microcontroller unit.

The microcontroller immediately shut down the particular generator and starts the next generator. Now the corresponding relay shares the second generator power with the load.

The user can understand the status of the troublesome generator and can be repaired. If any problem with the second generator, the microcontroller immediately shut down the second generator and starts the first generator.

The LED indicators indicates the status of the generator in working. Thus this project is very much used in industries to avoid power failures. The microcontroller used in this project is PIC16F73. The microcontroller program is written in assembly language
