More DetailsPower Factor - Inductive Load. The power factor of an AC electric power system is defined as the ratio active (true or real) power to apparent power, where. Active (Real or True) Power is measured in watts ( W) and is the power drawn by the electrical resistance of a system doing useful work. Apparent Power is measured in volt-amperes (VA) and ...

More Details· Power factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA). Apparent power, also known as demand, is the measure of the amount of power used to run machinery and equipment during a certain period. It is found by multiplying (kVA = V x A).

More Details· For example, the circuit shown in figure 4-10 has a total reactance of 80 ohms capacitive and the power factor was .6 or 60 percent. If 80 ohms of inductive reactance were added to this circuit (by adding another inductor) the circuit would have a total reactance of zero ohms and a power factor …

More Details· Chris Mullins. Jun 28, 2017. True power factor (PF) and displacement power factor (DPF) are commonly available on power analyzers and loggers. At first glance (and in some situations), they appear to measure the same thing, but there is an important difference. A review of their definitions and an explanation of when to use each are presented here.
