Many approaches can be taken when evaluating the replacement of PCB-filled capacitors on overhead distribution feeders. Pennsylvania Power and Light Company utilized the opportunity to reevaluate capacitor application techniques as well as capacitor placement. This paper summarizes a joint PP&L/Westinghouse effort to determine the value of a complete capacitor engineering evaluation as compared with a strict one-for-one unit replacement. Examination of seven feeders yielded significant reduction in real line losses, formulating the justification for future capacitor application efforts.
