Abstract

Kraftbelastede høyspenningsledninger (2) er elektrisk brutt ved hjelp av en skilledel (3) som opptar kreftene i ledningene. En strøm-sensor- innretning (4) er koblet elektrisk parallelt med skilledelen (3). Målesignalene blir optisk overført over en lysleder (9), som er innført i en fleksibel isolator (6) med jordpotensial. Fordel: høy jordskjelvssikkerhet, potensialadskillelse.
