Power failure is a common problem. It hampers the production of industry, construction work of newplants and buildings. It can be overcome by using a backup power supply such as a generator. But it is costeffective and also time consuming as certain time is required to switch on the generator manually. It is oftennoticed that power interruption in distribution system is about 70% for single phase faults while other two phasesare in normal condition. Thus, in any commercial or domestic power supply system where 3 phases available, anautomatic phase selector system is required for uninterrupted power to critical loads in the event of power failurein any phase. There is no requirement of backup power supply in that case. Also, there is no time consumption asthe phase is changed automatically within a few seconds. The main aim of this paper is to present the real idea ofan automatic phase switch for 220V to 240V alternating current. Although, there are many designs that canperform almost similar functions like, single phase change-over switches, two phase automatic transfer switchand three phase automatic change-over switch, but this model is about an automatic phase switchover (phaseselector) which is designed for only three phase A.C input power to single phase output applications.
