for those of you who want to "geek out" on power factor correction &
reactive power,

here are couple of links that give understandable explanations

http://home.earthlink.net/~jimlux/hv/pfc.htm
http://www.ambercaps.com/lighting/po...n_concepts.htm
http://www.nepsi.com/powerfactor.htm

the "best" power factor correction is achieved by adding "balancing"
capacitors at each inductive load (motor)

cheers
