Hello guys,
please give me ideas of how to make transformer turns ratio tester using null detector bridge.
the theme would be that i have to apply ac voltage to HV side of transformer suppose 11000V, and then maybe 415V will be induced on secondary side of transformer. So, turns ratio at this stage would 11000/415*1.732=45.908 .... so having 6 tapping transformer, turns ratio would be different for all taps... i want to feed these turns ratio values to my null detector bridge and as i energize the transformer, whatever value will be induced on secondary side should be shown on my bridge circuit, or null detection indication.... please guide me how to do that...
