Abstract
An apparatus is for visual indication of an energized state of electrical conductors. The apparatus includes two electrodes structured to capacitively couple to two energized electrical conductors, respectively, in order to harvest an electric field. A rectifier is powered from one or both of the two electrodes. An illuminated indicator or a non-illuminated indicator is powered from the rectifier.
Claims26
An apparatus for visual indication of an energized state of electrical conductors, said apparatus comprising:
- two electrodes structured to capacitively couple to two energized electrical conductors, respectively, in order to harvest an electric field;
- a rectifier powered from at least one of said two electrodes;
- and
- an illuminated indicator or a non-illuminated indicator powered from said rectifier.
An apparatus for visual indication of an energized state of electrical conductors, said apparatus comprising:
- two electrodes structured to capacitively couple to two energized electrical conductors, respectively, in order to harvest an electric field;
- a circuit powered from said two electrodes;
- and
- a non-illuminated indicator powered from said circuit,
- wherein said two energized electrical conductors are energized by a direct current voltage;
- and
- wherein said non-illuminated indicator is a contrast ratio indicator.
