Abstract:
An apparatus is provided for securing to and collecting power from an electrical conductor including a wire clamp that clamps to and secures the apparatus to the electrical conductor, a current transformer (“CT”) that clamps to the electrical conductor and collects power from the electrical conductor, and a housing including a cavity that encloses circuitry associated with the apparatus. According to various aspects, the circuitry may include one or more sensors and wireless communications circuitry, and the CT may include a core and an electrical winding that receives an induced current from magnetic flux generated according to alternating current present on the electrical conductor.
Abstract:
A communicating faulted circuit indicator (“FCI”) apparatus, as well as methods for using the apparatus. A sensor is configured to collect data relating to a state of an electrical conductor. A controller is logically coupled to the sensor and configured to receive the data collected by the sensor and to determine whether to communicate the collected data to a location remote from the FCI. A communications facility is logically coupled to the controller and configured to communicate the data to the remote location in response to the controller's determination to communicate the data to the remote location. The communications facility can include a cellular communications device. The remote location can comprise a cellular communications device. The remote location also can be a computer system configured to receive communications from the FCI.
