The most basic explanation of the power factor of induction melting furnace

Example of induction melting furnace: The power of the induction melting furnace is 100 units, that is, 100 units of power are delivered to the induction melting furnace. However, due to the inherent reactive power loss of most electrical systems, only 70 units of power can be used. Unfortunately, although only 70 units are used, 100 units have to be paid. In this example, the power factor of the induction melting furnace is 0.7 (if the power factor of most induction melting furnaces is less than 0.9, it will be fined by the electric industry department), this kind of reactive power loss mainly exists in the motor or the induction melting furnace ( Such as blowers, pumps, compressors, etc.), also called inductive loads. Power factor is a measure of motor performance.
