The purpose of this project is to monitor and control various electrical devices within the transformer. The parameters that will be monitored include the voltage, current, frequency and circuit breaker status.. It also trips the circuit breaker whenever necessary. This project consists of a Microcontroller based control system. The analog and digital inputs from respective are sent to the microcontroller. Microcontroller process this raw data and converts into human readable format and displays on LCD display.  Microcontroller continuously checks the data being read and takes necessary action if the read values exceed the preset limits. The action could be opening of a circuit breaker.  

The objectives of the project include:  

1. Monitors voltage, current of Substation devices.
2. Produces buzzer alerts.
3. LCD displays the alert messages based on the user requirements.

  The project provides us exposure on:  

1. Initialization of ADC module of microcontroller.
2. Embedded C program.
3. PCB designing.
4. Employing different electrical sensors.
5. LCD interfacing.

The major building blocks of this project are:

1. Microcontroller.
2. Regulated power supply.
3.  Relay
4. LCD
5. Buzzer.
