BS EN 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. This standard is applicable to the complete voltage range.This standard does not apply to capacitors of the self-healing metallized dielectric type.The following capacitors, even if connected in series with a circuit, are excluded from this
standard:capacitors for inductive heat-generating plants (IEC 60110-1);capacitors for motor applications and the like (IEC 60252 (all parts));capacitors to be used in power electronics circuits (IEC 61071);capacitors for discharge lamps (IEC 61048 and IEC 61049).For standard types of accessories such as insulators, switches, instrument transformers,
external fuses, etc. see the pertinent IEC standard.NOTE 1 Additional requirements for capacitors to be protected by internal fuses, as well as the requirements for
internal fuses, are found in IEC 60143-3. See also Annex C.NOTE 2 Additional requirements for capacitors to be protected by external fuses, as well as the requirements for
external fuses, are found in Annex A and Annex C.NOTE 3 A separate standard for series capacitor accessories (spark-gaps, varistors, discharge reactors, currentlimiting
damping reactors, damping resistors, circuit-breakers, etc.), IEC 60143-2, has been revised and was
completed in 2012. A separate standard for internal fuses for series capacitors, IEC 60143-3 has been revised and
was completed in 2013.NOTE 4 Some information regarding fuseless capacitor units and fuseless capacitor banks is found in Annex C.The object of this standard is:to formulate uniform rules regarding performance, testing and rating;to formulate specific safety rules;to serve as a guide for installation and operation.Cross References:IEC 60050IEC 60060-1:2010IEC 60071-1:2006IEC 60071-2:1996IEC 60143-2:2012IEC 60143-3:1998IEC 60143-4:2010IEC 60549:2013IEC 60871-1:2014IEC 62271-1:2007IEEE Std. 693:1997EN 60060-1:2010EN 60071-1:2006EN 60071-2:1997EN 60143-2:2013EN 60143-3:1998EN 60143-4:2010EN 60549:2013EN 60871-1:2014EN 62271-1:2008IEC 60060-2:2010IEC 60110-1:1998IEC 60252-1:2010IEC 61048:2006IEC 61049:1991IEC 61071IEC 60270:2000IEC 60909-0:2001EN 60060-2:2011EN 60110-1:1998EN 60252-1:2011EN 61048:2006EN 61049:1993IEEE Std 824-1994ANSI C29.9:1983EN 61071EN 60270:2001EN 60909-0:2001All current amendments available at time of purchase are included with the purchase of this document.
