Dwv testing cables
WebAlthough the the dielectric withstand test and the insulation resistance test are similar, insulation resistance tests generally run below 1000 Vdc and return a value in ohms, while dielectric withstand test voltages can run up to 5000 Vac and 6000 Vdc depending on the requirements and returns a value in milliamps. WebThe dielectric withstanding voltage (DWV) test puts a mechanical strain on the insulation by forcing the electrons and nuclei in the insulation from their normal positions. A DWV test failure is detected when a discharge, expressed as leakage current, exceeds a defined leakage current set point.
