Dimensional tolerances of ferrite cores not-eligible Higher voltages are allowed at

Higher voltages are allowed at the discretion of the manufacturer provided the insulation is not damaged due to overstress by the voltage applied

Note 1: Immunity requirements are given in the frequency range 0 Hz to 400 GHz

The electrical power supply of a tractive unit is achieved by the collection of current from the contact wire using one or more pantograph(s)

— eluates of sediment (freshwater

but rather identifies generic processes applicable to all these incidents

PD IEC TR 63090 is a document that discusses dimensional tolerances of ferrite cores, as a result of which manufacturers and suppliers can ensure their products are fit for purpose. PD IEC TR 63090 gives guidelines on the dimensional tolerances of ferrite cores that are generally used by ferrite core suppliers. As a reference, this is useful for ferrite core suppliers and users
