Anotation

IEC 60851-5:2008 specifies the following tests: - Test 5: Electrical resistance; - Test 13: Breakdown voltage; - Test 14: Continuity of insulation; - Test 19: Dielectric dissipation factor. Significant revisions to the previous edition include the following points: - In Subclause 5.3, the addition of the use of carbon brush electrodes for the counting discontinuities during the high voltage continuity test, as an alternative to the V-groove pulley electrode; and - Clarifications in the breakdown voltage test for round wires larger than 2,500 mm and for fibrous covered wires. La CEI 60851-5:2008 donne les methodes dessai suivantes: - Essai 5: Resistance electrique; - Essai 13: Tension de claquage; - Essai 14: Continuite de lenveloppe isolante; - Essai 19: Facteur de dissipation dielectrique. Les modifications significatives par rapport a ledition precedente comprennent les points suivants: - Au Paragraphe 5.3, lajout de lutilisation des electrodes balais en carbone pour le comptage des discontinuites pendant lessai de continuite sous haute tension, comme alternative a lelectrode poulie ayant une gorge en forme de "V"; et - Des clarifications apportees a lessai de la tension de claquage pour les fils de section circulaire avec diametre nominal du conducteur superieur a 2,500 mm et pour les fils guipes de fibre.
