Power factor is the ratio of real power over total power, where total power includes the vector sum of real and reactive power.
Resistors use real power. Perfect capacitors and inductors store power. In an AC system, capacitors and inductors will begin collecting power as the voltage applied to them increases, but eventually the voltage applied to them will be less than the charge they are already holding, and they will discharge into the circuit. This shows up as a phase shift in current relative to voltage.

What is a system that links electricity produced in power stations to deliver it to where it is needed?
Power Systems or Transmission & Distribution
What is APFC panel?
An Automatic Power Factor Correction (Controller) panel is used to Save Energy by consistently maintaining higher power factor. Low Power Factor leads to poor power efficiency, thereby increasing the apparent power drawn from the distribution network. This results in overloading of Transformer, Bus bars, Switch gears, Cables and other distribution devices within the Industry or consumer area.With an APFC the energy producer can:Avoid Penalization for lower power factor.Enjoy incentives for higher power factor operation being extended to Industries by some Electricity Boards/ Companies.Optimize the connected load for improved plant load factor.Avoid manual disruption.Avoid high current consumption losses.Improvement in voltage regulation.Decrease Maximum Demand KVA, thus avoiding penalty and Demand Charges.
Why unity power factor is used in load test?
When power factor is at unity, the voltage and current waves are aligned or in phase with one another. Since power is the product of voltage and current, power transfer is maximized at unity power factor. When power is transmitted at a lower power factor, greater current is required to deliver the same amount of power. When current is increased, the size of the transmission, distribution and generation systems, all have to be increased accordingly, along with the price of the killowatt-hour at the meter.
Does raising the power factor of a residence result in dollar savings on your electric bill?
No. Your energy meter monitors the supply voltage and the in-phase component of the load current, so improving your power factor will have no effect on your energy consumption and, therefore, your electricity bill.
What is ACDB panel?
ACDB stands for alternating current distribution board. A distribution board or panel is part of an electricity supply system. The panel splits the power up into circuits. At the same time, it uses fuses or circuit breakers to provide protection from electrical overload.
