  • Embedded pole part for medium or high voltage use, with a vacuum interrupter which is embedded into an insulating resin
    Patent number: 10460893
    Abstract: An embedded pole part for medium or high voltage use, with a vacuum interrupter which is embedded into an insulating resin, wherein a current and/or voltage sensor with sensor housing is integrated inside the insulating resin. In order to overcome the problems of the art, and to enhance the accuracy of voltage measurement, a metal grid is implemented into the insulating resin, which is arranged between the sensor housing of the current and/or voltage sensor and the outer surface of the insulating resin.
    Type: Grant
