Partial discharge tester PD 4020L

The PD 4020L partial discharge tester helps to test insulation materials and insulation systems for their insulation strength. Whether testing individual insulating materials, such as plastics or paints, or testing components from the drive train, such as stators or connectors, whether in the laboratory or in production, whether in small or large series: The PD 4020L is suitable for all environments and requirements and delivers the most sensitive measurement results with precise repeatability!

The partial discharges, excited by an external hipot or surge tester, can be detected with active measurement technology both by radio and inductively. Radio measurement technology is the first choice for open test objects such as a stator. For closed or shielded DUTs, such as inverters or motors, partial discharges can be measured by inductive measurement via the connection cables of the DUT.

The various measuring procedures, which are adapted to the DUT, can be conveniently carried out using our DAT 3805 control software. The measurement technology is designed in accordance with the DIN EN 60270 and 60664-1 standards and can be used under almost all production conditions without any problems! The device also masters the IEC 61934 measurement method!

Note on Calibration for Surge Test and Partial Discharge Measurement
Factory calibrations can only be performed according to our specifications. For the Surge Test, this includes checking the generator voltage at three voltage levels, measuring (with oscilloscope ) the displayed surge voltage at three voltage levels, and checking the time scale with a test surge using the Dummy D4010. For the Partial Discharge Measurement, three level values are simulated and checked with our CR 4000 Simulator.
