Abstract

The purpose of this project is to design a hybrid voltage and frequency monitoring device which can act as a controlled power source. The whole system which is controlled and monitored by the ATC89c51 microcontroller, provides a perfect monitoring of line voltage and frequency and alerts the user for critical voltage and frequency limits and switches off the electromagnetic relay that act as a Circuit Breaker to switch off the main electrical supply to protect the electrical circuitry. The Relay gets activated whenever the electrical parameters are within the limited predefined acceptable ranges. All the circuit breakers like MCB etc. available in market cuts the power only in the exceeding voltage ranges but this system can cut the power when frequency is exceeded from ±10% of the normal supply frequency (50Hz, AC) as well as upper and lower cutoff voltages 250V and 160V respectively. Thus better protection of electrical circuitry is possible by this system.
