Single Phase Preventer Using Microcontroller
Abstract
The aim of this project is to construct a single phase monitor and prevention system using 8-bit microcontroller .Anti-single phasing relays or single phasing preventer are required for critical loads and circuits. These are required because the normal overload protection doesn’t trip on time. For large air-conditioning compressors, irrigation pumps these are sometimes included.
The purpose of this project is to develop an intelligent system that continuously monitors all the three phase voltage (High voltage Ac) and if any of these three phases is disconnected then this system takes the prevention action. The preventive action could be disconnecting the power supply immediately to the load by operating an electromagnetic relay. This system also alerts the user using visual and audible indicators.
