To calculate the power in Kilowatts (KW) from Kilovolt-Amps (KVA):
\[ KW = KVA \times PF \]
Where:
KVA (Kilovolt-Ampere) and KW (Kilowatt) are units of power. KVA measures apparent power, which includes both real power (KW) and reactive power (KVAR). KW measures real power, which is the actual power used to do work. The conversion from KVA to KW is done by multiplying KVA by the power factor (PF), a unitless number between 0 and 1. This factor represents the fraction of the total power that is effectively used for work. Understanding this conversion is crucial for accurately determining the real power consumption of electrical systems.
Assume the following values:
Using the formula:
\[ KW = 50 \times 0.8 = 40 \]
The power is 40 Kilowatts (KW).
Assume the following values:
Using the formula:
\[ KW = 75 \times 0.9 = 67.5 \]
The power is 67.5 Kilowatts (KW).
