ABSTRACT:
Measurements are taken perimetrically about power or feeder cables at equidistant spaced locations with one or more vibration transducers feeding an electronic measuring circuit sharply tuned to twice the fundamental frequency of the supply system. A substantially flat response around the cable indicates a deenergized cable, while an energized cable produces vibrations that vary sinusoidally in amplitude as the readings progress around the cable.
