Method for the analysis and monitoring of the partial discharge behavior of an electrical operating means

摘要

Partial discharge data is kept in process status matrices (1), in each of which the amplitude (7) for a partial discharge, its phase angle (6) and its frequency of occurrence are mapped in a matrix element (5) for a process status matrix (PSM) . Partial discharge process statuses are detected in first and consecutive PSM at first and consecutive time points. An Independent claim is also included for a device for carrying out the method of the present invention.
