    摘要: A sensor apparatus for detecting leakage current in a post-type insulator of an electrical power system includes: a sensor unit having a housing, the sensor unit including: a sensor assembly operable to generate an analog signal proportional to a received leakage current; an electronics module operable to covert the analog signal to a digital value; and a communications system operable to wirelessly transmit the digital value to an external receiver; a collection band adapted to be connected to an exterior surface of the insulator; and a transfer lead interconnecting the sensor assembly and the collection band, the transfer lead operable to transfer leakage current from the insulator from the collection band to the sensor assembly.

    摘要: An electric power transmission system that isolates a local AC transmission network from a surrounding AC system includes a local AC load center having a plurality of local AC loads, and a distribution feeder serving the plurality of local AC loads and at least one distant electric power generating station or other power source for supplying AC power to the local AC load center. A complete or partial DC transmission ring is interposed between the local AC load center and the distant electric power generating station for isolating the AC power received from the distant electric power generating station from the local AC load center by converting the AC power to DC power. The DC power is re-converted into AC power based on load requirements and the distribution feeder supplies the AC power while all local AC loads are isolated from the distant electric power generating station.
