Power factor controller have different types that are optimized to served specific requirements in the industry. Power factor controllers are the heart and brain of operation for power factor correction which is a kind of energy saving methods. In this topic I am going to discuss on how to install the power factor controller. These are the steps:

In alternating current system (AC) we are dealing with three types of power. These are the following:

1. Real power (P) by which its unit is expressed in watts (W).

2. Reactive power (Q) by which its unit is expressed in reactive volt-amperes (VAR).

3. Apparent power (S) by which its unit is expressed in volt-amperes (VA).
