Abstract

The activities of manufacturing, telecommunication, medicine, etc, requires power for driving various equipment. Most often, the electrical power sources used in powering this equipment either suffers voltage or frequency fluctuations which leads to malfunctioning or outright destruction of the equipment. This article presents a system that monitors the quality of power supplies, checks for fluctuations in voltage and frequency on the power sources available and then connects the load to the purest source of the power. The system consists of four (4) basic units, namely: power sources, power supply, controller and displays. In the display unit are the liquid crystal display (LCD) and light emitting diode (LED). The power supply unit provides the Vcc to all other units. The system’s control is a micro-controller, built around the Arduino uno, which follows a set of instruction to identify the source with the purest power and connects it to the load. The system was tested on the three power supply sources, two of which were infested with forced impurities, one voltage fluctuation and the other frequency fluctuation, while the third source was without the aforementioned defects. The system selects the third power source that is void of the fluctuation and displays 50Hz and 230V on the LCD.
