fact to deter-mine the amplitudes of the harmonicsto which the distortion is due. Forsimplicity, suppose the third harmoniconly to be present, and let E be thereading of the voltmeter and / that ofthe ammeter (Fig. i). If E1 and ^represent the emfs of the fun-damental and harmonic, then we may… … Fig. 1. i^EipC;i3=E3.spC; Ek-=E1t+El we thus have four equations connecting Eu E3, iu i3, from whichthese four quantities may be calculated. This is the inverse ofthe process sometimes employed in correcting for wave form, forexample, in the 3-voltmeter method of measuring inductance.Theoretically,…
