Abstract
A system for indicating a power condition in a conductor includes an indicator constructed to provide notification to a user of a utility power condition, and a sensor non-electrically connected to a utility conductor to control operation of the indicator in response to detection of power in the utility conductor.
Claims34
A power indicator constructed to be connected to an electrical enclosure that receives primary power from a main conductor, wherein the electrical enclosure includes one or more walls defining an interior, the power indicator comprising:
- a sensor electrically isolated from the main conductor and operative to sense the supply of primary power in the main conductor, wherein the sensor comprises a housing and a sensor wire that extends from the housing, wherein the housing is configured to be secured to one of the walls of the electrical enclosure and wherein the sensor wire is adapted to be positioned adjacent the main conductor and senses the supply of power to the main conductor;
- and
- indicator circuitry contained within the housing and connected to the sensor wire, wherein the indicator circuitry is configured to provide a sensory indication of the supply of power to the main conductor.
A power restoration indicator for an electrical system that includes an electrical enclosure with one or more walls defining an interior;
- one or more electrical circuits contained within the interior of the enclosure, and a main conductor extending into the interior of the electrical enclosure and interconnected with the one or more electrical circuits for supplying electrical power to the one or more electrical circuits from a main power supply, wherein the power restoration indictor comprises:
- a housing configured to be secured to one of the walls of the electrical enclosure;
- a sensor wire that extends from the housing, wherein the sensor wire is electrically isolated from the main conductor and is adapted to be positioned adjacent the main conductor to sense the supply of power to the main conductor;
- an alert contained within the housing and interconnected with the sensor wire;
- and
- indicator circuitry contained within the housing and connected to the sensor wire, wherein the indicator circuitry is configured to activate the alert when power in the main conductor is detected.
