Power factor is a measure of degree to which a given load
matches that of a pure resistance.
Power factor is a ratio of actual power(VIcosΦ) to apparent
power(VI), so it is given by cosΦ.
PF=1 (for resistive load).
PF=0 (for both inductive and capacitive load).
PF leads with capacitive load and lags with inductive load.

If we connect a motor and generator together (I mean that the generator gives the motor electricity and the motor gives the generator movement) regardless the losses. Will the generator still generate and the motor still move?
WHAT IS MEANT BY TV TERMINAL IN 500MVA TRANSFORMER?
In our plant we have installed new MCC with ELR and CBCT which is detecting some leakage current in the system but it leading to some confusion when to check that in which feeder which is drawing current we put off the whole panel itself but still CBCT detecting some leakage current so can anybody ans me , where i am going wrong or how to detect whether its actual leakage or CBCT malfunctioning.
