kVA vs kW — Understanding the Difference

 kVA vs kW — Understanding the Difference ⚡

In electrical engineering, it’s important to distinguish between apparent power (kVA) and real power (kW).
🔹 kVA (Kilovolt-Ampere)
 • Represents the total power drawn from the source
 • Includes both real power and reactive power
 • Used in rating equipment like transformers, UPS, and generators
🔹 kW (Kilowatt)
 • Represents the actual useful power that performs work
 • Excludes reactive components
 • Used in motors, heaters, lamps, and other loads
✅ Simply put:
 • kVA = Apparent Power (capacity of the system)
 • kW = Real Power (usable power)
This difference is essential for power system design, efficiency analysis, and load management.
