Description of BS EN 60143-1:2015 2015This part of IECÂ 60143 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 15Â Hz to 60Â 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:
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, current-limiting 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:
