Abstract: 

This paper presents a feasibility study on measure voltage harmonics with a contactless device, on multi-conductor cables. The demonstration is given by a four-conductor cable with a variety of standard dimensions, using an external calibration signal, given the capability to adjust itself “on field”. The results show the proposed methodology is suitable to be used in an electronic circuit; even with many random sources of error, simulated in the environment test.

Keywords: 

contactless voltage measurement, harmonic voltage measurement, power quality, harmonic distortion.
