Auto Selection of any Available Phase in 3
Auto Selection of any Available Phase, in 3 Phase Supply System
Auto Selection of any Available Phase, in 3 Phase Supply System Introduction Ø 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 misses. Ø The three transformers are connected to the 3 phases supply. It automatically switch to next phase while one phase is misses. Ø For monitoring the phase shifting we are using NAND gate logics. Ø The relay driver IC to change the load to the next phase through the contacts those are fed from all the three phases. Ø At final condition it works on inverter. http: //www. edgefxkits. com/
Auto Selection of any Available Phase, in 3 Phase Supply System Working Ø Three phase supply are given to three independent transformers connected in together with another transformers from receiving supply, an inverter. Ø The secondary of the transformers are used to develop DC by half wave rectification and then deriving four number of opto isolators individually. Ø The DC supply from all the three phases and inverter supply are combined and then fed to the regulator IC 7805 for the circuit operation power. Ø The relays connected drive the load with interlocking logic from the NO/NC contact such that the 1 st phase load automatically changes over to any available phase in the event http: //www. edgefxkits. com/
