how to calculate the current if i know power in MW and
voltage 11kv/415v and also want to know that incoming
cables for trnsformer
Answer Posted / sripellirajukumar
hi this is rajkumar...
as per my knowledge
the primary side current can be calculate as follows
for example
we have power transformer of 5MW transformer and the 33\11kv
the primary current is (5000kv/33kv)/1.732=87.47amps
the secondary current is (5000kv/11kv)/1.732=262.43amps
here 1.732 is square root of 3....

i have a 4 Mva transformer 34.5 kv / 480-277 v and i used 2 parallel 3200 amp bus duct for the secondary feeder using 3 ply of bus bar ( 3/8" x 5" ) as a common where the flexible link terminated and 6300 amps breaker for the main, the lower bus duct reaches 70 degrees and the upper bus duct reaches 55 degrees when i used thermal scanner. why the temperature is not balance when the load reaches 3600 amps.

Some times to change of DOR of a motor, interchange of R & B is not effected and RYB take same current, but interchange of R&Y is effected ie change the DOR. My doubt is what is the problem in motor and how it is happen.
