ECN Forum Forums Technical Discussion Electrical Theory and Applications Sizing Power factor caps?

If the customer is being billed on a KW demand then there is no need to install the caps. They won't reduce the demand charge.

Dnk
If the main is only a 400 amp I doubt that there is a KVA demand. Probably a KW demand.
If there is a KVA demand charge, I think installing the caps at the main will be a cheaper installation. How did you measure the PF at the panels?
