This assures an excellent simulation of the transient stresses of motor windings and coils through high dynamic drives and controls (i.e. PWM inverters), according IEC 60034-18-41 and IEC TS 61934.<br \/>\nIn addition to the turn and layer short test of windings, it allows easy and fully automatic partial discharge tests within a coil for applications in production, QC and research\/lab as well as predictive diagnostics. This includes the recording of PD inception\/extinction voltages (PDIV-PDEV) with a new software algorithm.<br \/>\nThrough the special filter method with plane patch antenna and narrowband filter circuit (1.7 GHz band), all disturbing noises and frequencies become masked while maintaining high signal sensitivity.<br \/>\nThis allows usage of the instrument in complex automatic test systems and production environments without harming the signal quality.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The new system is based on our automatic state of the art Impulse Winding\/Surge Tester of DWX series.
