To calculate the power in watts:
\[ P = S \times PF \times 1000 \]
KVA (Kilovolt-Ampere) and Watts are both units of power, but they measure different types of power. KVA is a unit of apparent power, which includes both the real power (measured in watts) and the reactive power (which is not used, but is necessary to maintain the voltage levels in the system). The relationship between KVA and Watts is defined by the power factor of the electrical system. The power factor, which ranges from 0 to 1, represents the percentage of the electricity that is being used to do useful work. If the power factor is 1, then all the power is being used effectively, and the KVA is equal to the Watts.
Let's assume the following values:
Step 1: Multiply the apparent power by the power factor:
\[ S \times PF = 10 \times 0.8 = 8 \]
Step 2: Multiply the result by 1000:
\[ P = 8 \times 1000 = 8000 \text{ watts} \]
Let's assume the following values:
Step 1: Multiply the apparent power by the power factor:
\[ S \times PF = 15 \times 0.9 = 13.5 \]
Step 2: Multiply the result by 1000:
\[ P = 13.5 \times 1000 = 13500 \text{ watts} \]
