In AC electrical systems, phase-shifting between voltage and current introduces the concept of complex power, which has active power, reactive power, and apparent power as its components. Understanding complex power is fundamentally important for AC electrical system analysis, operation, a...
What is active power (P) Active power (P) also known as “real power” or “active power” is the useful power that is used within the AC circuit. What is reactive power (Q) Reactive power (Q) is not used but is transported between the source such as a power station and the loa...

Power factor (pf) is the difference between real power and apparent power. This is greatly misunderstood but important for the buyer to know. Historically, most large UPSes had a pf of 0.8, which meant a 100 kilovolt-Ampere (kVA) UPS could only deliver 80 kW of real power. Most of ...
