40、ating Safety requirements Guidance for installation and operation 1 Scope and object This part of IEC 60252 applies to motor capacitors intended for connection to windings of asynchronous motors supplied from a single-phase system having a frequency up to and including 100 Hz, and to capacitors to b

41、e connected to three-phase asynchronous motors so that these motors may be supplied from a single-phase system. This standard covers impregnated or unimpregnated capacitors having a dielectric of paper, plastic film, or a combination of both, either metallized or with metal-foil electrodes, with rat

42、ed voltages up to and including 660 V. Motor start capacitors are covered by IEC 60252-2. NOTE The following are excluded from this standard: shunt capacitors of the self-healing type for a.c. power systems of up to and including 1 000 V nominal voltage (see IEC 60831-1); shunt capacitors of non-sel

43、f-healing type for a.c. power systems of up to and including 1 000 V nominal voltage (see IEC 60931-1); shunt capacitors for a.c. power systems having a nominal voltage above 1 000 V (see IEC 60871-1); capacitors for induction heat-generating plants, operating at frequencies between 40 Hz and 24 000

44、 Hz (see IEC 60110-1); series capacitors (see IEC 60143); coupling capacitors and capacitor dividers (see IEC 60358); capacitors to be used in power electronic circuits (see IEC 61071); small a.c. capacitors to be used for fluorescent and discharge lamps (see IEC 61048); capacitors for suppression o

45、f radio interference (IEC publication under consideration); 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 a.c. voltage. The object of this standard is a) to formulate uniform ru

46、les regarding performance, testing and rating; b) to formulate specific safety rules; c) to provide a guidance for installation and operation. 2 Normative references .The following referenced documents are indispensable for the application of this document.
