The combined surge voltage and partial discharge tester ST 3820K has been specially developed for integration into automatic test systems and for use in the laboratory. It is ideally suited for detecting winding shorts and insulation faults within a winding, even before the fault affects the electrical specifications of the DUT. By combining a surge voltage generator with partial discharge measurement technology, the ST 3820K provides you with a compact, all-in-one solution for insulation testing of winding materials.
Due to the extremely steep voltage rising edge and the different, optionally available, surge capacities, the ST 3820K is ideally suited for conventional wound goods (e.g. wound stators) as well as for wound goods in the field of e-mobility (e.g. hairpin stators).
The partial discharges, excited by the surge tester, can be detected with active measurement technology both by radio and line. 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 DUT's connecting cables.
The standardized test procedure according to IEC 61934 for determining the insulation parameters PDIV, RPDIV, RPDEV and PDEV can be performed with the ST 3820K in a flash.
