Relations between Reactive power,power factor and penalty Power Factor penalty is spelled out in the contract between the Power Company and Industrial or Commercial customer with large three phase loads. If the contract calls for 85% Power Factor, once the customer’s power factor falls below 85%, the Power Company bills the Customer according to the agreed penalty rates. Industrial loads are mostl...
