This part of IEC 60931 is applicable to both capacitor units and capacitor banks intended to be used, particularly, for power-factor correction of AC power systems having a rated voltage up to and including 1000 V and frequencies 15 Hz to 60 Hz.
This part of IEC 60931 also applies to capacitors intended for use in power filter circuits. Additional definitions, requirements, and tests for filter capacitors are given in annex A.
The following capacitors are excluded from this part of IEC 60931:
– Shunt power capacitors of the self-healing type for AC systems having a rated voltage up to and including 1000 V (IEC 60831 series).
– Shunt capacitors for AC power systems having a rated voltage above 1000 V (IEC 60871).
– Power Capacitors for induction heating installations (IEC 60110 series).
– Series capacitors for power systems (IEC 60143 series).
– Capacitors for motor applications (IEC 60252 series).
– Coupling capacitors and capacitor dividers (IEC 60358).
– Capacitors for power electronics (IEC 61071).
– Small AC capacitors to be used for fluorescent and discharge lamps (IEC 61048 and IEC 61049).
– Capacitors for suppression of radio interference (under consideration).
– Capacitors intended to be used in various types of electrical equipment and thus considered as components.
– Capacitors intended for use with DC voltage superimposed on the AC voltage.
– Shunt power capacitors of the self-healing type for AC systems having a rated voltage above 1000V (IEC 63210).
Accessories such as insulators, switches, instrument transformers, fuses, etc., are to be in accordance with the relevant IEC standards.
The purpose of this part of the IEC 60931 standard is:
a) to formulate uniform rules regarding performances, testing and rating;
b) to formulate specific safety rules;
c) to provide a guide for installation and operation.
