To convert from kVA (kilovolt-amperes) to kW (kilowatts), you need to know the power factor (pf) of the system. The formula is:
\[
\text{kW} = \text{kVA} \times \text{Power Factor (pf)}
\]
If the power factor is 1 (which is the case for purely resistive loads like heating elements), then:
\[
\text{kW} = 10 \, \text{kVA} \times 1 = 10 \, \text{kW}
\]
However, if the power factor is less than 1 (which is common for inductive loads like motors), you'll need to multiply the kVA by the power factor value. For example, if the power factor is 0.8:
\[
\text{kW} = 10 \, \text{kVA} \times 0.8 = 8 \, \text{kW}
\]
So, the conversion depends on the power factor of the load. If you know the power factor, you can use it in the formula above.
\[
\text{kW} = \text{kVA} \times \text{Power Factor (pf)}
\]
