Description
Automating feature is now the need of the day. It is user friendly and easy to use. It saves time too. This kit 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.
This system can used to automate the electrical system where switching is required. It also serves for the safety in heavy industrial duty. Manual changeover can be replaced by automatic change over in home. The main part of the kit is microcontroller. We have to convert the 220 V ac supply to 5 v dc from each phase. This 5v supply is given to microcontroller and it is programmed to fulfill the above requirements. The output of the microcontroller is given to ULN2803 relay driver. The relay finally selects the phase in terms of ac voltage.
