Automatic power factor correction using Arduino

The power factor of an AC electrical system is the measure of how closely a particular load equals the resistance of a pure resistance. It's a proportion of a load's an average power to a resistive load's an average power for much the same voltage and the current scale, with a value between 0 and 1. An active power is the actual quantity of the power utilized or lost in a circuit, and it is measured in watts. The product of the sine voltage and current waveforms called an active power. The energy consumption in the ac circuit due to the inductive and capacitive fields is known as the reactive power. KVAR is the unit for measuring the reactive power. The sum of the active and reactive power is known as an apparent power. It's the sum of a circuit's voltage and current without taking the phase angle into the account. The volt-amps unit is used to measure the apparent power(S) (VA). It is more powerful than both active and reactive power. Because of the reactive power. which is the electric charge in the circuit and is negative, or because the current lags the voltage by a phase angle and returns to the supply, or because of a misaligned load, the produced a wave from the power source is distorted. The perfectly resistive load has a power factor of one Because the sine voltage and current waveforms are in the phase, or the phase angle variation between both the voltage and current is 0. The power factor is expressed in kilowatts. Reactive power doesn't quite produce beneficial "work," but rather flows between both the generator and the load during times when the system is required to function properly. In kilo volt amperes, reactive power is measured (kVA). It is visible power when active and reactive power are combined. In kilovolt-amperes, the perceived power is measured (kVA).
