Hello guys, what are the benefits and disadvantages of having a leading power factor
The question is the wrong way round. There is no advantage, there is disadvantage to positive or negative PF.
Helius has tried to explain this.
I like to explain it like this:
AC has changing voltage. At some point the voltage crosses 0V.
It takes voltage to 'push' current through circuits.
When the Voltage is at 0V, there is no voltage ('presure') to push current through the circuit.
So if you have a circuit that requires current at the 0V point, it becomes very difficult to get current to flow.
This is the reason utility compannies charge more when you are out of phase.
PFC is to re-align your power draw to the AC waveform.
Hope that helps
