Abstract
En måleanordning (10) for måling av spenning i en høyspenningsdel (22) som er omgitt av et elektrisk felt, omfatter en kapasitiv føler (11) og en signal- omformer (13 ). Føleren omfatter en indre elektrode (12) med en omgivende skjerm- elektrode (14). I skjermelektroden, som er koplet til et kontrollerbart re- feransepotensial, er det anordnet en åpning (16) som under måling rettes mot høyspenningsdelen (22). Ved hjelp av avføling av en rettet del av det elek- triske felt som trenger gjennom skjerm- elektrodens åpning og inn i den indre elektrode, måles høyspenningsdelens (22) spenning på isolasjonsavstand.A measuring device (10) for measuring voltage in a high voltage part (22) surrounded by an electric field comprises a capacitive sensor (11) and a signal converter (13). The sensor comprises an inner electrode (12) with a surrounding shield electrode (14). In the display electrode, which is coupled to a controllable reference potential, an aperture (16) is arranged which during measurement is directed to the high voltage part (22). By sensing a directed part of the electric field which penetrates through the opening of the screen electrode and into the inner electrode, the voltage of the high voltage part (22) is measured at an insulation distance.
