If we give the 440 V supply at secondary winding of the transformer then what will affect at primary winding???????
6 6707If 440 V supply has given at the secondary winding of transformer at that time if we apply 11 KV at primery then what will happen???????

How to synchoronize the generator (with gcb,GT) to grid????? ????? from Grid iam getting power (rated 400kv/20kv) through GT and its goes to UAT.,,ST.,, now my generator(rated 20kv ) ready.,, now iam closing my GCB.,, in GT iam suddenly giving 20kv on that Gt.,, what will happend

I have a current transformer with 1 main reading meter with transformer outside the building and a control panel having 5 CT reading meters with black round coils inside the building. I want to know, A) when current pass through the Transformers, will the current be reduced or be the same and after that B) when current pass through the CT meters with black round coils, will the current be reduced or be the same. C) in the above process will the reading of the main meter be same or different, from the total reading of all the 5 CT meters.

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
