Power Factor

Power factor is a factor that measures the efficiency of electrical equipment. The low power factor indicates that the reactive power of the circuit for alternating magnetic field conversion is large, thereby reducing the utilization rate of the device and increasing the line power loss.

In the power triangle, the ratio of the active power (P) to the apparent power (S) is called the power factor cosφ, and its calculation formula is: P=U*I*cosφ, where φ refers to the phase difference between voltage and current. And cosφ is the power factor.
