Answer / manoj

Transformer is a static equipment which is not directly
loaded so its power factor is unity. so its rating is in kva
and not in kw

For refrigerators the motor current is raised beyond its rating on both conditions when the voltage of the system is more(say 270v) than the rated voltage(220v) as well as when the voltage of system is less(say 160v) than normal voltageof 220v, why explain?
