Abstract
A portable instrument for locating and measuring harmonic distortion in a conductor. The instrument permits voltage and current harmonics to be easily read while the load is changing. Thus, the instrument may provide a great deal of insight as to the source of problem causing harmonics.
Claims14
Apparatus for locating and measuring harmonic distortion in a conductor, comprising:
- first means detachably connectable to a conductor for providing an input signal indicative of electrical energy in said conductor;
- second means connected to said first means and receiving said input signal therefrom, said second means providing a modified signal indicative of the strength of a single, predetermined harmonic of said input signal;
- third means connected to said second means for selectively varying the single, predetermined harmonic which is indicated by said modified signal;
- and
- said modified signal indicates voltage harmonics.
