Abstract—The partial discharge (PD) is defined in the international standard IEC 60270:2000 as a localized electrical discharge. The IEC definition is largely academic and it isn’t oriented to practical purpose. It should be noted that the PD investigation is aimed to search for the (potential) defects that are PD sources and assess their dangers. The traditional PD conception is analyzed from this point of view. It is shown that if the theory of the apparent charge is useful for case of single discharge it is not useful in general for common case of the set of discharges.
