- Abstract
When the partial discharge within insulation system of generator stator occurs, there are several methods to detect the signal of such dangerous discharge. First the global method detecting discharge current impulse and second the method based on detecting of discharge emitted electro-magnetic energy. The indirect measuring of current discharge using inductive probe is described in this paper. This method uses inductive probe which output is analyzed by digital measuring oscilloscope technique and software specially developed to partial discharge detailed analysis. Instead of common global test there is necessary to use special localization method, as described above, for analyzing the ratio of partial discharge activity within particular stator slot of electrical rotating generator and its stator slots respectively. Method of inductive probe in differential setup is very useful to this diagnostics of rotating machines.
