Abstract
An indicator system for an alternating current power bus includes an electret operatively associated with the alternating current power bus. The electret includes an output having an alternating current voltage when the alternating current power bus is energized. A rectifier includes an input electrically interconnected with the output of the electret and an output having a direct current voltage responsive to the alternating current voltage of the output of the electret. An indicator includes an input electrically interconnected with the output of the rectifier and an indication output responsive to the direct current voltage of the output of the rectifier.
Claims22
