Reactive power
Active power can be measured by inserting a wattmeter into the circuit. To calculate the reactive power, the formula for calculating the reactive power (Q) can be used: Reactive power (Q) = √ (S^2 – P^2), with: Q: Reactive power in volt-amperes-reactive (VAR). S: Apparent power in volt-amperes (VA).

Superconducting Magnetic Energy Storage: Status and Perspective
Abstract — The SMES (Superconducting Magnetic Energy Storage) is one of the very few direct electric energy storage systems. Its energy density is limited by mechanical considerations to a rather low value on the order of ten kJ/kg, but its power density can be extremely high. This makes SMES particularly interesting for high-power and short ...
