For any given frequency your inductive load must exactly balance your capacitive load so that the net phase change on the current is zero. This condition is also known as resonance.

Z (impedence) = R (resistance) + jωL -1/jωC

where ω=2πf (2*Pi*frequency)

Yes, It is important to understand Why, when & where.

Need to take care of UPS, DG, other equipment which are designed for 0.8 pf lag.

If you will send me your e-mail I will send you a copy of a Power Factor and Harmonic correction technical primer that I published earlier this year. My E-Mail addressis kendalld@stacoenergy.com
