This part of IEC 60358 applies to:
• Capacitors, with rated voltage > 1 000 V, connected line to ground with the low voltage
terminal either permanently earthed or connected to devices, for applications listed
hereunder and other similar uses.
This standard serves as basic standard for the coupling capacitor, the different parts of this
standard will present the supplementary specifications and tests, for example IEC 60358-2,
IEC 60358-3 or IEC 60358-4.
