Series capacitors for power systems - Part 1: General
IEC 60143-1:2015 applies both to capacitor units and capacitor banks intended to be used connected in series with an a.c. transmission or distribution line or circuit forming part of an a.c. power system having a frequency of 15 Hz to 60 Hz. The primary focus of this standard is on transmission application. The series capacitor units and banks are usually intended for high-voltage power systems.…
Condensateurs série destinés à être installés sur des réseaux - Partie 1: Généralités
L'IEC 60143-1:2015 s'applique aux condensateurs unitaires et aux batteries de condensateurs destinés à être raccordés en série sur une ligne de transport ou de distribution d'énergie faisant partie d'un réseau alternatif de fréquence comprise entre 15 Hz et 60 Hz. L'objectif principal de cette norme est de traiter des applications sur les réseaux de transport. Les…
Low-voltage surge protective devices - Part 22: Surge protective devices connected to telecommunicat...
IEC 61643-22:2015 describes the principles for the selection, operation, location and coordination of SPDs connected to telecommunication and signalling networks with nominal system voltages up to 1 000 V r.m.s. a.c. and 1 500 V d.c. This standard also addresses SPDs that incorporate protection for signalling lines and power lines in the same enclosure (so called multiservice SPDs). This second…
