b. Si les exigences d'essai ci-dessus n'existent pas, la tension d'essai doit au moins \u00eatre conforme aux exigences 1) ou 2) suivantes et ne doit pas s'interrompre pendant au moins une minute. <\/p>\n\n\n\n
1) Pour les \u00e9quipements \u00e9lectriques dont la tension d'alimentation de cr\u00eate ne d\u00e9passe pas 90 V ou dont la tension de cr\u00eate interne ne d\u00e9passe pas 90 V, la valeur efficace de la tension d'essai est de 500 V ; <\/p>\n\n\n\n
2) Pour les autres mat\u00e9riels \u00e9lectriques ou les mat\u00e9riels dont la tension de cr\u00eate interne d\u00e9passe 90 V, la valeur efficace de la tension d'essai est la plus \u00e9lev\u00e9e des valeurs suivantes : 2 U + 1000 V ou 1500 V.<\/p>\n\n\n\n
Il est permis d'utiliser une tension d'essai continue \u00e0 la place de la tension d'essai alternative sp\u00e9cifi\u00e9e. Pour les enroulements isol\u00e9s, elle doit \u00eatre \u00e9gale \u00e0 170% de la valeur effective de la tension d'essai CA sp\u00e9cifi\u00e9e, ou pour le d\u00e9gagement \u00e9lectrique ou la ligne de fuite dans le milieu isolant, elle doit \u00eatre \u00e9gale \u00e0 140% de la valeur effective de la tension d'essai CA sp\u00e9cifi\u00e9e. <\/p>\n\n\n\n
Note : U est la valeur la plus \u00e9lev\u00e9e de la tension d'alimentation nominale ou de la tension la plus \u00e9lev\u00e9e qui se produit \u00e0 l'int\u00e9rieur de l'\u00e9quipement. <\/p>\n\n\n\n
Pour les \u00e9quipements dont les composants sont isol\u00e9s \u00e9lectriquement, la tension d'essai doit \u00eatre appliqu\u00e9e \u00e0 chaque composant s\u00e9par\u00e9ment \u00e0 la tension appropri\u00e9e.<\/p>","protected":false},"excerpt":{"rendered":"
