Abstract

En elektrisitetsmåler omfatter minst en strømførende leder (4, 5, 6) og en nøytral ledningsstropp, idet de respektive innløp og utløp for den strømførende leder samt for den nøytrale ledningsstropp er anordnet parallelt med hverandre og i samme plan inne i målehuset. En metallskinne (13) som er koblet til nøytrallederen er anordnet inne i målehuset i nærheten av i kort avstand fra innløpet og/eller utløpet for den strømførende leder (4, 5, 6) for å danne et gap (124, 125l 16) hvori en regulert lysbue kan dannes mellom den strømførende leder og metalskinnen i tilfelle en overspenning.
