Answer Posted / gourav jaswal
kw is actual power.
kva is apprent power.
The main diffrence b/w these two is power factor,
kw = kva * p.f
Normaly p.f cant be calculated before in any AC system, so
that it measured in kva.
Same as in case of t/f its also have rating in kva (not in kw)

A 50Hz,4-pole,3-phase,star-connected synchronous motor has a synchronous reactance of 12ohmsper phase and negligible armature resistances.the excitation is such as to give an open-circuit voltage of 13.2kilovolt.the motor is connected to 115kilovolt, 50hertz supplying. what maximum load can be the motor torque,line current and power factor?
I have a current transformer with 1 main reading meter with transformer outside the building and a control panel having 5 CT reading meters with black round coils inside the building. I want to know, A) when current pass through the Transformers, will the current be reduced or be the same and after that B) when current pass through the CT meters with black round coils, will the current be reduced or be the same. C) in the above process will the reading of the main meter be same or different, from the total reading of all the 5 CT meters.
