|Publication Date:||6 August 2018|
The methods given herein include direct and indirect determinations of active power (watts), reactive power (vars), and power factor produced or consumed in alternating-current single-phase and polyphase electrical circuits, electrical generators, power transformers, and motors. This Supplement does not include such measurements of fundamental electrical properties as voltage, current, frequency, resistance, and impedance, except as needed to support the objectives of this Supplement.
