AC Resonant PD Test System
An AC resonant test system for AC withstand-voltage and partial-discharge testing of XLPE power cables and other high-voltage products. The adjustable-reactor configuration is selected around the capacitance of the test object.
- AC withstand-voltage and partial-discharge testing.
- Adjustable reactors to match test-object capacitance.
- System selection by voltage, capacity and test duty.

Technical Specifications
| Reference parameter | Catalogue value |
|---|---|
| Rated voltage range | 100–1500 kV and above, by configuration |
| Rated capacity range | 300–30000 kVA and above, by configuration |
| Partial discharge | ≤2 pC at 80% of rated test voltage |
| Rated-capacity duty | 1 hour on / 1 hour off; 3–6 cycles per day |
| Below 50% capacity | Continuous operation, per catalogue |
The voltage and capacity ranges describe the catalogue family, not a single universal system. PD performance includes the stated 80% rated-test-voltage condition; the test object, connections and site conditions must be defined for acceptance.

Questions About This Machine
Does the ≤2 pC figure apply at full rated voltage?
The catalogue specifies ≤2 pC at 80% of rated test voltage. It should not be restated without that condition.
Is kVA the same as impulse energy?
No. kVA is the AC system capacity unit here. The separate impulse test system specifies rated energy in kJ.
