) to correct your power factor is by using the following trigonometric formula: power correction factor calculation

The most direct way to calculate the required reactive power ( Qccap Q sub c Qc=P×(tan(ϕ1)−tan(ϕ2))cap Q sub c equals cap P cross

The is the mathematical process used to determine the exact size of a capacitor bank (measured in kVAR) required to bring a system's power factor to a desired target (usually 0.95 or higher). 1. The Power Factor Correction Formula : The actual real power load (measured in kW)

: The required capacitive reactive power (measured in kVAR). : The actual real power load (measured in kW). ϕ1phi sub 1 : The phase angle of the current power factor ( ϕ2phi sub 2 : The phase angle of the target power factor ( 2. Step-by-Step Calculation Process

In an AC electrical system, the measures how effectively you use electricity. A low power factor means you are drawing more current than necessary to do the same amount of work, which often leads to utility penalties and increased equipment wear.
