DANSK DSF/PREN IEC 63210 PDF

This IEC standard is applicable to both self-healing capacitor units and self-healing 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 fundamental frequencies of 15 Hz to 60 Hz. The following capacitors are excluded from this IEC standard: • Shunt power capacitors of the self-healing type for a.c. systems having a rated voltage up to and including 1 000 V (IEC 60831-1, -2). • Shunt power capacitors of the non-self-healing type for a.c. systems having a rated voltage up to and including 1 000 V (IEC 60931-1, -2 and -3). • Shunt capacitors of the non-self-healing type for a.c. power systems having a rated voltage above 1 000 V (IEC 60871-1, -2, -3 and -4). • Capacitors for inductive heat-generating plants operating at frequencies between 40 Hz and 24 000 Hz (IEC 60110-1 and -2). • Series capacitors (IEC 60143-1, -2, -3 and -4). • AC motor capacitors (IEC 60252-1 and -2). • Coupling capacitors and capacitor dividers (IEC 60358-1, -2, -3, -4). • Capacitors for power electronic circuits (IEC 61071). • Small a.c. capacitors to be used for fluorescent and discharge lamps (IEC 61048 and IEC 61049). • Capacitors for suppression of radio interference. • 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. Accessories such as insulators, switches, instrument transformers, external fuses, etc., should be in accordance with the relevant IEC standards and are not covered by the scope of this IEC standard.
