Early Warning for DC Power Failure System

Abstract:

Article Preview

Electrical systems and devices suffer from unexpected failures due to various reasons such as input voltage fluctuation and low or high voltages. This paper discussedabout the development of a device for detecting imminent failure of electric products such as refrigerators, ovens, Air-conditions and etc. The main objective of this developed preventive device is todetect voltage drop or rise and produce an alarmsignal to enable and activates other protection circuitry.The mechanismof the detector/sensing circuit is based on differentiating the voltage level using dualcomparator; this makes the system more considerate. The method enables real-time monitoring of stability boundaries and the corresponding margin to the observed operating point, which is used to provide an early warning for emerging stability problems.
