How to convert from volts to kW in 1 single step

Step 1:

To change from volts to kW you only have to multiply the variables shown in the formula, according to the type of DC or AC current and the number of phases and then divide by 1000. For example: A biphasic web server has a 120V voltage (AC, LN), a power factor of 0.89 and a current of 7.2Amp, how many kW does the server have ?.

To know the answer you should only take the formula to find biphasic kW by multiplying the variables as follows: 2x120x7.2 x 0.89 = 1.54kW (Formula: kW = 2xV (LN) xIxF.P).


Examples of conversions from volts to kW:

Example 1:

A three phase refrigerator has an AC voltage of 230Volts (LL), 5.7Amperios and a power factor of 0.83, how many kW does the vacuum cleaner have?

Rta: // What you must do is identify the formula to be used, since the equipment is three phase and AC (alternating current), you should use the formula: √3xV (LL) xIxF.P / 1000, replacing the variables would be : √3x230Vx5.7 × 0.83 = 1.88kW.

Example 2:

A biphasic sodium luminaire has an AC voltage of 240V (LL), an amperage of 7.7Amperes and a power factor of 0.91, which will be the power in kW of the luminaire ?.

Rta: // Check the formula for biphasic equipment (Formula: kW = 2xV (LN) xIxF.P / 1000), because we have the LL voltage, we must pass it to LN, in the following way: multiply 220V (LL) / √3 = 138V (LN), this is the way in which the voltage from Linea-Linea to Linea-Neutro is converted, then we simply multiply the variables that appear in the formula: 2x138x7,7 × 0.91 = 1.67kW.

Example 3:

The three-phase voltage in an office is 380Volt (LL), a power factor of 0.84 and an amperage of 163Amp, how many kW does the office have?

Rta: // As it is a three-phase iluminaicon the formula must be taken: (√3xV (LL) xIxF.P = watts), then replacing the variables I get: √3x380x163x0,84 / 1000 = 90.12kW.
