Abstract
The methodological aspects of the assign and use parameters of the equivalent circuit connected to study of partial discharges (PD) are discussed. The problem of ''apparent charge'' as an applied regulatory parameter connecting with the true charge of the PD is studied. Equivalent circuit for the calibration and measuring apparent charge are analyzed and the corresponding matrix model based is created. It is shown that the ''apparent'' and true charges are reflected in the circuit equations as independent of each other parameters, and connection between them is merely a heuristic. The traditional model of a spherical bubble in a homogeneous external electric field is analyzed and boundary conditions of its correctness is studied. The question about to estimate the value of the maximum charge is analytically investigated. It is shown that the available analytical and experimental evaluation of apparent charge substantially different from the true theoretically possible charge. It was concluded that from a scientific point of view, the PD model on the basis of the concept of ''apparent charge'' has exhausted itself.
