| Zusammenfassung: | The resistive element (1) includes a central segment (2) of constant cross-section and two terminal parts (3, 4) made of copper brazed on to the central segment along two junctions (6, 7) transversal to the direction of passage of the current, equipped with lugs (8, 9) constituting the means for series connection, the said central segment (2) being made of a material having a resistivity higher than that of the copper by at least one order of magnitude, and exhibiting a resistivity variation as a function of temperature not exceeding 25 ppm/@C, at least between -20@C and +80@C. Use especially in electrical energy meters for distribution mains. |
