Abstract
A non-contact voltage probe is used to measure the voltage of electromagnetic interference developed in a cable or the like electrically connected to pieces of electronic equipment. The non-contact voltage probe has double coaxial cylindrical-type inner and outer electrodes through which a cable or the like is passed. The inner electrode is electrically connected to a voltage detector, which measures the voltage induced by the capacitance between the inner electrode and the cable passing there through, and the outer electrode is grounded.
