Answer / iamdon
Power factor is the factor by which real power differ from
the apparent power.That is why it is called power factor.Real
power can NEVER BE GREATER than the apparant power.Since the
apparent power remains fixed,it is the power factor, which
decides the amount of real power calulation in the network.
That is why power factor is so much of importance in electrical
engineering.
Real power=(power factor)*(apparant power)
W = (pf) * (VA)

what is the relationship between phase & neutral
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.

A powerplant has 8 gensets operating in grid parallel mode. In one genset sometimes there is pf variation and kvar variation. The plant operates in pf mode. When this variation is observed the load is stable, voltage is also stable, freq and genset speed is also stable. How will you check the functioning of pf card. What shall be the ideal output vdc of the pfc, from there it is input to AVR?
