The Phase change over can only is installed with three-phase supply. The selection of Phase change over is done according to the mains load. This kit automatically gives output of all the three phase either one or two phases are missing, and after the return or present of all three phase it diverts automatically to its originating phase.
Automating feature is now the need of the day. It is user friendly and easy to use. It saves time too. This project is also a proto-type to automation of the system. In the earlier days (even today at some places) the manual operations are frequent. When the main supply goes off the person manually turn on the generator. In case of the electrical appliance control using automation causes more safety. This kit is a prototype for the same which is auto change over to generator when main supply fails. In this system we are designing an embedded circuit to control this. In case there are two phases, then the switching will be in the default phase. Three relays are there to control the switching.
