Could someone advise the actual effects on the ac induction motor.....
<<Regarding the ac motor, please, see my posting as a response to your posting at other place.>>

what is the power consumption by a single system(load)in kw and kva?
<<It can be both. It depends on many factors. Many loads have kW on their nameplates, e.g. heaters, lamps, small motors, ac drives, etc. Others have kVA, e.g. motors, transformers, etc.
kVA and kW are tied by relationships posted above in most cases that do not deal with harmonics and power quality.
suppose we have a load of 17000w what is the equivalent kva?.
<<kVA = 17000 Watts x power factor / 1000>>

WHAT IS THE DIFFERENCE BETWEEN KV AND KVA ?
<<kV is a unit or dimension for voltage, and kVA is unit or dimension for Apparent or complex power.>>
IS THERE ANY CONVERSION FACTOR BETWEEN THE TWO?
<<Yes, there is a difference since kV is a unit for voltage and kVA is a unit for apparent power. Obviously, the voltage is different from power; however, they are related by several relationships, e.g.
Power kVA = Voltage kV x Current A, or
Power kVA = (Voltage kV)**2/Impedance Z
for simple one phase (single phase) circuit and associated connected load.
