What is reactive power?
Answer: Power factor correction will reduce electricity cost only, when the plant receiving power from a common grid carries out the correction at the supply voltage/incoming voltage level, just to compensate for the reactive power drawn from the grid. But, even this improvement in PF may not always reduce the electricity cost as the …

Reactive power
In some cases, special circuits are used to measure the reactive power. For example, the reactive power measurement can be performed with compensation capacitors to determine the amount of reactive power compensation. Here, capacitors are added or removed to minimize the phase shift angle and thus compensate for the reactive power.
