Under Voltage and Over Voltage Monitor to Protect the Electrical Load

This research paper is presented to design a system that will monitor and protects the electrical loads from under voltage and over voltage supply, which may be due to unforeseen adverse effects of electrical voltages or voltage fluctuations. These adverse effects of voltage will affect the power quality that is being supplied to the electrical loads. Power quality can be defined as a steady supply voltage that stays within the prescribed ranges without the adequate/prescribed range of power supply; the electrical loads may malfunction, overheat, fail prematurely, or not operate at all, subsequently it is very vital to ensure that the correct range of voltage is being supplied to electrical loads. With this system in place, any adverse effects of voltages, by activating its tripping mechanism if the voltage supplied to the loads is not within the desired range/limits and safely isolate the electrical loads.
