if we going for high voltage usages what are the considering factors, why those factors are effected.... please give me an answer related motor factors like wnidnig, frame, temp etc
ABB,
1 1746we done magnetic balance test for 33KV /440V transformer in our company , but the ratio out is confusing us Voltage applied in RY = 440 , at RB = 320 and YB = 60 RY 440 = ( RB + YB ) 380 only Please let me know what type of problem is it.
