15 kV Impulse Winding Testing for High-Voltage Coil Evaluation
The ECG KOKUSAI DWX-15 and DWX-15PD extend the DWX impulse winding tester platform to applications requiring test voltages up to 15 kV.
Both models compare the transient response of a test winding with a stored master waveform to evaluate winding condition and insulation-related differences. The DWX-15PD adds microwave-based partial discharge detection for applications requiring additional discharge evaluation.
