DESCRIPTION

IEC 60549:2013

IEC 60549:2013 applies to external fuses used with high-voltage capacitors according to IEC 60871-1, Shunt capacitors for a.c. power systems having a rated voltage above 1 000 V - Part 1: General. IEC 60871-1 is applicable to both capacitor units and capacitor banks intended to be used, particularly, for power-factor correction of a.c. power systems, and also to capacitors intended for use in power filter circuits. Fuses according to IEC 60549:2013 are intended to clear either faults inside a capacitor unit to permit continued operation of the remaining parts of the bank in which the unit is connected (unit fuses) or faults on the whole capacitor bank to isolate the bank from the system (line fuses). This second edition cancels and replaces the first edition published in 1976. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - alignment of the document with current IEC document structure requirements; - clarification of certain test requirements. Keywords: external fuses used with high-voltage capacitors, shunt capacitors for a.c.power system
