Bulletin 1724D-112
Distribution capacitors can reduce system line losses, as long as the system power factor is not forced into a leading mode. Line losses at 80% leading power factor are just as detrimental as line losses at 80% lagging power factor. Properly placed and sized capacitors can usually reduce system line losses sufficiently to justify
