how to decide the ratings of the busbar in
electrification.give me the proper thumb rule or procedure
Answer Posted / kannapa
busbar I = 1.4xtransformer kva this is apparent power.
busbar I = 1.74xtransformer kva this is for load in kw.
actual this is on low votage i.e., 415v 3phase only.
p=1.732xvxI from this we can obtain for different votages
and power ratings.
v may be 11kv,415,220v etc

at work we have a 3 phase motor but on testing one phase isnt getting a reading. it runs 24 hours a day all week. stops and starts well no noise or heating. the phase isnt down to earth.is it just a bad meter reading or not? phases one and three came up with a resistance reading of 0.4 but phase 2 couldnt get anything shows up as open circuit.
