Compact 30kV 0.1 Hz cosine square wave testing system for PD detection on XLPE cables

In working condition, cable as capacitive load is charged to a default voltage through positive DC source firstly, and it’s in the part of square wave. Thus, load begins to discharge via inductance and load capacitor, and voltage polarity of load reverses. It’s worth mentioning that energy of load is recycled under the discharge process. The typical waveform is shown in Figure 2. Specific process is depicted as follows
