CAN/CSA-C871-1-98 (R2002)

1. Scope This standard is applicable to capacitor units and capacitor banks intended to be used in particular for power-factor correction of a.c. power systems having a rated voltage above 660 V and a frequency of 15 Hz to 60 Hz. It is also applicable to capacitors intended for use in power filter circuits. Notes 1. - Additional definitions, requirements and test for filter capacitors are given in Appendix C. 2. - Additional requirements for capacitors to be protected by internal fuses, as well as requirements for the internal fuses, are given in IEC Publication 593. 3. - Requirements for capacitors to be protected by external fuses, as well as requirements for the external fuses, are given in Appendix D. 4. - This standard is not applicable to high-voltage capacitors composed of low-voltage capacitors of the self-healing metallized dielectric type. Additional definitions, requirements and tests for self-healing capacitors will be found in the future IEc Publication XXX. 5. - The following are also excluded from this standard: - Shunt capacitors for a.c. power systems of up to and including 660 V rated voltage (IEC Publication XXX, in preparation). - Capacitors for induction heat-generating plants, operating at frequencies between 40 Hz and 24 000 Hz (IEC Publication 110). - Series capacitors (IEC Publication 143). - Capacitors for motor applications and the like (IEc Publication 252). - Coupling capacitors and capacitor dividers (IEC Publication 358). - Capacitors to be used in power electronics circuits (IEc Publication YYY under consideration)). - Small a.c. capacitors to be used for fluorescent and discharge lamps (IEC Publication 566). - Capacitors for suppresion of radio interference (IEc Publication ZZZ (under consideration)). - Capacitors intended to be used in various types of electrical equipment and thus considered as components. - Capacitors intended for use with d.c. voltage superimposed on the a.c. voltage. 6. - Accessories, such as insulators, switches, instrument transformers, external fuses, etc., shall comply with the relevant IEC standards.
