if a transformer is of X VA then it means that this is the
burden of secondary side and also we knoe that this output
power is limited by the losses namely the core loss
depending on V and ohmic losses depending on I hence the
rating is given in VA. Consider a case where the power
factor of the load is ZERO hence the power delivered will be
zero but losses will still be there ...hence the output
varying with the condition ...but whats constant is VA.

need to make a report. Need to choose a 3phase induction motor. Load conditions motor will operate in : Maximum Load: 30 Kw Speed: 2950 rpm Ambient temp: 20 cent Supply voltage: 440V Frequency: 50Hz need to look for the safety factor when choosing the motor, went through catalouge found a few, but dont know how to choose the safety factor allowing an extra load something above 30 KW to avoid any harm.

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.
