International Standards and Conformity Assessment for all electrical, electronic and related technologies



Reference EN 60143-1:1993
Title Series capacitors for power systems - Part 1: General - Performance, testing and rating - Safety requirements - Guide for installation
Project Number 544
Abstract/Scope 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 series capacitor units and banks are usually intended for high voltage power systems. This standard is applicable to the complete voltage range. Note:For internal fuses for series capacitors, see EN 60595.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
