IEC 60110-1:1998 pdf download – Power capacitors for induction heating installations – Part 1: General.
This part of IEC 60110 is applicable both to indoor capacitor unit5 and indoor capacitor banks intended to be used, particularly, for power factor correction in induction heating, melting. stirring or casting installations, and similar applications with controlled or adjustable ac. voltage systems in a frequency range up to 50 kHz, and with a rated voltage not exceeding 3.6 kV.
Additional requirements br capacitors protected by internal element fuses are given in
IEC 60110-2.
The following capacitors are excluded Iron, this standard:
— series capacitors for power systems (see IEC 60143):
— capacitors for motor applications arid the like (see IEC 60252);
— coupling capacitors and capacitor dividers (see IEC 60358);
— shunt power capacitors of the self’healing type for a.c. systems having a rated voltage up to and including 1 000 V (see IEC 60831):
— shunt capacitors for a.c. power systems having a rated voltage above 1 000 V (see
IEC 60871):
— shunt capacitors of the non-self-healing type for ac. systems having a rated voltage up to and including 1 000 V (see IEC 60931);
— small ac. capacitors to be used tot fluorescent and discharge lamps (see IEC 61048 and
IEC 61049);
— capacitors lobe used in power electronic circuits (see IEC 61071);
— capacitors for microwave ovens (see IEC 61270);
— capacitors for suppression of radio interference (under consideration);
— capacitors intended for use with d.c. voltage superimposed on the ac. voltage
Accessories such as insulators, switches, instrument transformers, fuses. etc.. shall be in
accordance with the relevant lEG standards.
The object of this standard is:
a) to formulate uniform rules regarding performance, testing and rating;
b) to formulate specific safety rules:
C) to provide a guide for installation and operahon.
