Model No. 173: The basic idea for the development of the project is to provide supply to the single phase load if any of the phases, out of the 3 phases go missing. The kit is to be supplied with a 3phase power i.e., the three transformers are connected to the 3 phases supply. If any one of the phase is not available, the logic gates monitor the same at the low voltage of DC derived from ac of the secondary of the transformers to deliver output to the relay driver IC to change the load to the next phase through the contacts those are fed from all the three phases.
