Classification: CPC G  A | IPC G

Claim 15:
16. The demarcating system according to claim 15, wherein the predetermined current waveform are representable as a superposition of n sinusoidal current waveforms, each having a respective frequency fk and phase shift θk; and
wherein the operating voltage waveform are representable as a superposition of n sinusoidal voltage waveforms; and
wherein each of the sinusoidal voltage waveforms has the same frequency, fk, as a corresponding one of the plurality of sinusoidal current waveforms and has a phase shift that is a combination of the phase shift of that sinusoidal current waveform, θk, and an additional phase shift value, Φk,
wherein the instructions, when executed, further cause the one or more processors to determine Φk based on: the frequency of that sinusoidal current waveform, fk; the resonant frequency, f0, and one or more values corresponding to the other sources of resistance and/or capacitance within the same circuit as the wire loop.
