Abstract

Shunt-enhet for strømmåling dannet av et shunt-element (12) av en hovedsakelig sylindrisk form og av ZTC-materiale med et par strømkontakter i form av flate strimler (10, 11) festet til dens ender. Avfølingskontaktene (13, 14) til samme ZTC-materiale er fortrinnsvis forbundet med endene til shunt-elementet gjennom huller i kontaktene. Avfølingskontaktene kan danne en del av en kontinuerlig tråd som passerer gjennom et aksialt hull gjennom shunt-elementet. Alternativt kan det være dannet som en sammenhengende forlengelse av shunt-elementet.Current measurement shunt unit formed by a shunt element (12) of a substantially cylindrical shape and of ZTC material with a pair of flat strips (10, 11) connected to its ends. The sensing contacts (13, 14) of the same ZTC material are preferably connected to the ends of the shunt element through holes in the contacts. The sensing contacts may form part of a continuous wire passing through an axial hole through the shunt member. Alternatively, it may be formed as a continuous extension of the shunt member.
