In this paper the approach based on impulse analysis for partial discharge (PD) control and identification for high voltage insulation are summarized and the experimental research of impulses of different nature for detection some typical PD defects are discussed. Some physical effects at different voltage levels are shown and a method for the representation and characterization of the PD is introduced. Special test cells with different types of defects such as a streamer corona and pore inside oil-paper insulation of condenser type are used for the investigations. The experimental procedure for PD identification by means of impulse form transformation is shown and discussed. Experimental equipment and measurements are described. It is shown that using of impulse of nanosecond duration and commutative impulse allows the characterization and controlling PD in high voltage insulation.
