Examples of kVA to kW conversions:

Example 1:

A fan has a power of 5kVA, with a power factor of 0.85 and a voltage of 220Volts, how many kW does the fan have ?.

RTA: // It is simple you only have to multiply the kVA by the power factor, as follows: 5kVAx0.85, obtaining 4.25kW, in other words kW = 5kVAx0.85 = 4.25kW

Example 2:

There is a resistive load of an 80kVA furnace with a power factor of 1 and a voltage of 4160Volts, how many kW is the furnace ?.

Rta: // To know the answer you must multiply kVAxFactor power, as in the previous example, with which you will have 80kVAx1, which is equal to 80kW, as you can see commonly the resistive loads have the kVA equal to the kW (kVA = kW, in resistive loads).

Example 3:

An inductive load such as an air conditioner has a power of 25kVA, with a power factor of 0.83, which will be the power in kW of the air conditioning ?.

Rta: // You only have to multiply 25kVAx0.83, which will result in 20.75kW, as you can see in inductive loads such as motors, transformers, computers, elevators, air conditioners and in general equipment with motors and electronics you have power factors below 1, which would ensure that the kVA of these equipment is greater than kW.
