ELECTRONIC VOLTAGE REGULATOR:
The Electronic Voltage Regulator is designed and developed as per our client Tamilnadu Electricity Board Specification. The system is used in the Hydropower Generation Plant which is to regulate the generation of voltage as per the load requirement. More than 12 such system has been developed for the automatic control of voltage generation in hydropower generation plant.

WINDOW ANNUNCIATOR:
This project has been developed for Tamilnadu Electricity Board to Monitor the line voltage fault level. It has been designed based on ATMEL 89C52 Microcontroller. It consists of three switches namely TEST, ACK, and Functional RESET key. whenever there is no line voltage, the bulb corresponding to the output will blink to indicate that there is no source input or their is a line fault.
