WebReactive power “losses” are not negative. It’s just that (unlike non-reactive losses) their instantaneous values SUM TO ZERO OVER THE COURSE OF EACH CYCLE OF THE AC. To … WebFactors considered in feeder design include cost, real power losses, and voltage performance. A typical design goal is to keep average real power losses below 2%. At full output, real power losses can be higher, in the 3% to 5% range. Land use agreements usually favor the use of underground feeders despite the higher cost.
