IEC 62475-ed.1.0

Anotace textu normy IEC 62475-ed.1.0 :

IEC 62475:2010 is applicable to high-current testing and measurements on both high-voltage and low-voltage equipment. It deals with steady-state and short-time direct current (as e.g. encountered in high-power d.c. testing), steady-state and short-time alternating current (as e.g. encountered in high-power a.c. testing), and impulse-current. In general, currents above 100 A are considered in this International Standard, although currents less than this can occur in tests. This standard also covers fault detection during, for example, lightning impulse testing. La CEI 62475:2010 sapplique aux essais et mesures a haute intensite sur des materiels haute et basse tensions. Elle couvre les essais a haute intensite en courant continu et courant alternatif en regime etabli et de courte duree ainsi que des essais de courant de choc. De maniere generale, la presente Norme internationale prend en compte des courants de plus de 100 A, meme si des intensites moindres peuvent apparaitre dans les essais. La presente norme couvre egalement la detection de defauts, comme par exemple dans le cadre dessais aux chocs de foudre.
