What is the power factor?

A: Power factor refers to the ratio of active power to apparent power of an AC circuit. User electrical equipment under a certain voltage and power, the higher the value, the better the benefit, the more power generation equipment can make full use of. It’s often represented by cosine phi.

The size of the Power Factor (Power Factor) is related to the load nature of the circuit, such as incandescent bulb, resistance furnace and other resistance load power factor is 1, generally with inductive load circuit power factor is less than 1. Power factor is an important technical data of power system. Power factor is a factor that measures the efficiency of electrical equipment. Low power factor indicates that the reactive power of the circuit used for alternating magnetic field conversion is large, which reduces the utilization rate of the equipment and increases the power supply loss of the line. In AC circuits, the cosine of the phase difference between voltage and current (Φ) is called the power factor, which is represented by the symbol cosΦ. Numerically, the power factor is the ratio of active power and apparent power, that is, cosΦ=P/S.

All the energy metering modules developed and produced by Gensi Technology can accurately measure power factors, such as three-phase embedded energy metering module JSY-MK-333 and single-phase energy metering module JSY1003.
