Difference Between KW and KVA

Active power is noted in kilowatts (kW). It designates the nominal electrical power of electrical receivers (electrical appliances consuming electricity equipping a property) calculated according to the following formula:

P = U * I * cos Ï†
For a single-phase power supply, P being the power in Watt (W), U being the voltage in Volt (V), I the intensity in Amperes (A), cos Ï† the power factor

For example: a 6kVA meter can collect 6000 watts of power used at the same time

The subscribed power, corresponding to the apparent power (S), is expressed in kilovolt-amperes (kVA). It is determined by Enedis and with the customer when configuring the electricity meter and depending on the electrical appliances that make up the household or the premises of a company. Higher than the active power, it covers all the electricity needs of the premises. This is the power that a customer can demand from the grid at any given time, without realizing any power overshoot. It is the maximum value of an installation.

The subscribed power can be modified upwards or downwards. You must request it from your electricity supplier.

The subscribed power is listed on the bill, the active power is determined by adding the watts of all the devices in the premises.

The formula for calculating the subscribed power is as follows:

P / cos Ï† = S = U * I
By dividing the active power (kW) by the cos Ï† (also called the power factor), we obtain the apparent power (S) in kVA.
