This part of IEC 60871 is applicable to both capacitor units and capacitor banks intended to be used, particularly, for power-factor correction of a.c. power systems having a rated voltage above 1 000 V and frequencies of 1 5 Hz to 60 Hz.
This part of IEC 60871 also applies to capacitors intended for use in power filter circuits.Additional definitions, requirements and tests for filter capacitors are given in Annex B.
