## Formula to convert kVA to kW, single-phase, two-phase and three-phase

We will thoroughly analyze the formula from kVA to kW, clearly defining what each variable that composes it means, how they interrelate and what is the difference between them. The formula used for the conversion of kVA to kW is as follows: With this formula you can manually convert from kVA to kW, however if …

## The power factor values ​​for the most common equipment and appliances

The power factor is the ratio between the “useful” working power kW and the apparent power kVA, this measures the efficiency with which electric power is used and is related by this formula fp = kW / kVA. A high power factor allows efficient use of energy, while a low power factor indicates poor utilization …

## Definition Power Factor, Ampere, Volt, kVA, kW, Motor Efficiency and Horsepower.

Power factor: Power factor is the ratio of working power to apparent power. It measures how effectively electrical power is being used. A high power factor signals efficient utilization of electrical power, while a low power factor indicates poor utilization of electrical power. Power Factor is the cosine of the phase angle between current and …
