Abstract

A shunt assembly for current measurement is formed of a shunt element (12) of substantially cylindrical form and of ZTC material having a pair of current connectors in the form of flat strips (10, 11) attached to its ends. Preferably sensing connectors (13, 14) of the same ZTC material are connected to the ends of the shunt element through holes in the connectors. The sensing connectors may form part of a continuous wire passing through an axial hole through the shunt element. Alternatively, they may be formed as integral extensions of the shunt element.

Description

Pokiaľ je to žiadúce, môže byť bočníkový prvok jemne sústružený alebo brúsený po výrobe, aby sa presne nastavila jeho hodnota. Zvyčajne však bude táto hodnota zmeraná presne a použitá na získanie presných prúdových hodnôt z napätia meraného na bočníku.If desired, the shunt element may be finely turned or ground after manufacture to accurately adjust its value. Usually, however, this value will be measured accurately and used to obtain accurate current values from the voltage measured on the shunt.
