AC Resonant Test Set for Power Cable Variable Frequency Series Resonance Hipot Test Equipment for 10kV 35kV 110kV and 220kV XLPE Cable Testing

The AC Resonant Test Set for Power Cable is designed specifically for high-voltage AC withstand testing of underground and transmission power cables.

Power cables have significant distributed capacitance, especially when long cable sections are tested. A conventional AC test source may require substantial power capacity. A variable-frequency series resonant system is designed to handle this capacitive load efficiently.

The system can be configured for different cable voltage classes and lengths by selecting appropriate reactor combinations and operating frequency.
