Measurement Principles of the Reactive Current RMS Value and the Load Susceptance for Harmonic Frequency Meters

The current of a nonsinusoidal source applied to a nonresistive load contains a reactive component ir which can be decreased or even wholly compensated by a shunt reactance 1-port of parameters related directly to the load susceptances for harmonic frequencies Bn?? The reactive current rms value measurement is necessary for evaluation of the possibility of the source apparent power minimization, and the load susceptance measurement is necessary for the compensating equipment design. This paper presents the measurement principles for measuring these quantities.
