Kilowatts to Megavolt-Amperes Converter
How to Convert Kilowatts (kW) to Megavolt-Amperes (MVA)
To convert kilowatts (kW) to megavolt-amperes (MVA), you must account for the power factor (PF). The formula is:
KW to MVA Calculation Formula
The apparent power S in megavolt-amperes (MVA) is equal to the real power P in kilowatts (kW), divided by the product of the power factor and 1000:
S(MVA) = P(kW) / (PF ร 1000)Thus, megavolt-amperes are equal to kilowatts divided by the product of the power factor and 1000:
MVA = kW / (PF ร 1000)Example Calculation
If you have a power measurement of 500 kW and a power factor of 0.9, the calculation would be:
S(MVA) = (500 kW) / (0.9 ร 1000) = 0.5556 MVAApparent Power (MVA)
Megavolt-amperes (MVA) represent the total power supplied by the electrical system, including both real power and reactive power.
Real Power (kW)
Kilowatts (kW) represent the actual power consumed by a device, which performs useful work in an electrical system.
Power Factor (PF)
Power factor is the ratio between real power (kW) and apparent power (MVA). It indicates how effectively the electrical power is being converted into useful work.
Pro Tip
Always size your electrical systems based on MVA (apparent power) rather than kW (real power) to ensure your system can handle the total power requirement!
