Способы представления дифференциальных амплитудных спектров импульсов частичных разрядов в твердой изоляции

Abstract

Geometrical parameters and number of air inclusions in solid insulation are defined on the basis of the decision of equation Volterra only in case of monotonous change of differential peak spectra (􀈾PS) of pulses of partial dischargers. Otherwise the average parameters of air inclusions are defined. The estimation of quality of solid insulation is carried out by representation of set DPS in double logarithmic scale. Comparison of curves DPS is carried out on width of a strip of spectra of partial dischargers without mathematical processing.
