Power factor is the ratio of working power to apparent power. It measures how effectively electrical power is being used. To determine power factor (PF), divide working power (kW) by apparent power (kVA). In a linear or sinusoidal system, the result is also referred to as the cosine θ. PF = kW / kVA = cosine θ kVA.

1.Static capacitor: The power factor can be improved by connecting capacitors in parallel with the equipment operating at lagging power factor. The capacitor (generally known as static capacitor) draws a leading current and partly or completely neutralises the lagging reactive component of load current. This raises the power factor of the load. For three-phase loads, the capacitors

Customer ServiceAdd a comment | 5 $begingroup$ Current can only flow in a closed loop, so a series capacitor cannot keep reactive current from flowing through the distribution grid, which is the very thing that power factor correction seeks to avoid in order to avoid the resistive losses of that current travelling long distances through practical conductors. Basically, the only way a
Customer ServiceCapacitors play a pivotal role in correcting power factor, particularly in systems with inductive loads. This is because inductive loads cause the current to lag behind the voltage, leading to a poor power factor.
