Question 1

What is kVA?

Accepted Answer

kVA (kilovolt-amperes) measures apparent power in AC circuits. It equals kW only when power factor is 1.0.

Question 2

How do I convert between power units?

Accepted Answer

1 kW = 1.341 mechanical HP = 0.102 boiler HP = 0.284 refrigeration tons. For kVA to kW: kW = kVA × power factor (typically 0.8-0.95).

Question 3

What is power factor?

Accepted Answer

Power factor is the ratio of real power (kW) to apparent power (kVA), ranging 0-1. Motors and inductive loads have lower power factors (0.7-0.9), causing higher current draw.

Question 4

Why are there so many power units?

Accepted Answer

Different industries developed their own units: mechanical HP for engines, boiler HP for steam, refrigeration tons for HVAC, kW/kVA for electrical systems.
