The calculation of power factor is according to ratios of real power and total power. Lower power factor electric equipment representative have unnecessary busywork and harmonic components.

功率因数值的计算是根据实际消耗功率与视在消耗功率的比值为基准，因此功率因数不佳的电力设备即代表存在著不必要的虚功以及谐波成份。

Electronic equipment produces busywork and harmonic components that not only increase unnecessary loading and power consumption in public power equipment. But also harmonic components insert into public power system that causes deteriorating of power quality. Risks increase into break and mistake of precision instrument.
