how to carry out Magnetizing Current Test on Distribution transformer and what purpose we are doing this test. why transformer rating in always in KVA ? what ispositive, negative, zero sequence impedence? How ElCB tripping if Neutral touch with ground Why AC & DC capacitor are use in UPS ? why motor rating in KW? how to syncronize two dg sets
Why only sinusoidal ac voltages are generated?why not triangular or sawtooth?
In our factory so many iron pillors are exists for supporting the shed/Hangar. If do more no of earthings at one piller instead of doing more earth pits in many locations and running earth strip around the hanger, I can save the money. Please suggest this method is acceptable as per Is specifications though the Earth resitance of the farthest piller is with in the limits as per IS specifications.
When calculation of fault current and fault Kva is to be done,why always we use per unit value and why we consider the base kva?
why we are using earth pit in sub stations.?
why does rotor rotets?
