Abstract:
A non-contact probe for measuring harmonic distortion of a current in a conductor comprising:a rigid housing with an elongated dimension;a passive, non-contact voltage sensor carried within said housing wherein said sensor includes first and second capacitor plates for detecting a voltage difference therebetween, wherein the first and second capacitor plates are spaced apart so as to enable the first capacitor plate to be brought within proximity of an adjacent conductor, wherein said sensor senses a voltage present in said adjacent conductor when the first capacitor plate is brought within proximity of the conductor without contacting the conductor;a processor coupled to the first capacitor plate of said sensor for determining the presence of harmonics in the detected voltage as well as relative amplitude values thereof; andan output device coupled to the processor for displaying harmonic distortion in the detected voltage wherein said output device is positioned on said housing.
