The three-phase power calculator calculates the apparent, active and reactive power for three-phase AC systems.
Apparent power represents the total power delivered to a circuit. In three-phase systems, it's calculated using:
\[S = \sqrt{3} \times V_{L-L} \times I\]Where:
Unit: Volt-Ampere (VA)
Active power, also known as real power, represents the actual power consumed by the load to perform useful work:
\[P = S \times pf\]Where:
Unit: Watt (W)
Reactive power is the power used to maintain electromagnetic fields in inductive or capacitive loads:
\[Q = \sqrt{S^2 - P^2}\]Where:
Unit: Volt-Ampere Reactive (VAR)
