摘　　要：用感应式电能表测量并联电容器回路这样低功率因数的负载时,由于功率因数过小,使起动功率很小,导致计量误差过大。为此我们采用电能表的非标准接线来提高计量的准确性。并通过试验,验证了方法的可行性。The load such as paralleling condenser have low power factor, because the driving power of induction watt-hour meter is smaller, result in measure error added. So this paper puts forward the method of decreasing measure error via changing standard connect of induction watt-hour meter. Test indicates the method is simple and high accuracy.
