Automatic Transfer Switch |Automatic Changeover for Generator |How To Connect Automatic Change Over


Hi Friend today we will learn about ATS ( Auto Change over switch) If you’re new here on our channel so please subscribe our channel and press the bell icon. Thanks For ATS we need 2SP MCB, 2 Relay, 2 Contactor and 1Time delay relay. These 2 SP MCB we use Normal supply and Generator supply control. This relay we use for control Normal supply contactor and time delay we use how much time delay we require. This MCB and relay we will use for Generator contactor Here you can see the diagram of ATS through this diagram we will make connection and you will see how we make interlocking between Normal supply and Generator supply. So now we start wiring we give supply to MCB then output give to relay and relay common point As you can see here on diagram We take supply from relay NO point to Timer A1 and Timer common point Here we take supply from timer NO point to Generator Contactor NC point then NC point out put to Normal supply contactor A1 terminal. Here you can see our Normal supply Wiring Circuit is complete. Now we will do wiring for Generator supply here we have diagram through this we will do. Now we give supply to MCB of Generator supply then output give to Generator Relay A1 from A1 to R1 common point Here you can see on diagram From R1 we give supply to Normal supply contactor NC point then output give to R2 Common point then NO point output we give to Generator contactor A1 Now our circuit is complete. But we need to connect neutral wire Now we connect neutral wire to R1, Timer and Normal supply contactor A2 point. Here we connect neutral for Generator supply R2 and Generator contactor A2 point. Neutral wire we connect separate for bot circuit. Here we connect bot supply Normal also and Generator also. Before circuit testing we will set the time for delay.we already set the time 7 to 8 second. you can also change the time from variable. Now we will test the circuit now i close the MCB of Normal supply you can see our circuit is working. Now i close the MCB of Generator supply relay is on now but our normal supply already there so Generator contactor not on. When normal supply will off Generator contactor will work. See now we restore the normal supply our Generator contactor is off and normal supply relay on after delay time normal supply circuit will work. So friend if you think our today video is good so please like our video, subscribe our channel. Thanks If you have any question in your mind you can also give comment. Thanks for Watching our Video.
