Impulse Voltage Test System
An impulse voltage test system for lightning and switching impulse tests on power cables, transformers, high-voltage switchgear and other HV products. System selection depends on the test object, required waveform and energy.
- Lightning and switching impulse voltage tests.
- NI- or PLC-based automatic control configurations described in the catalogue.
- Measurement configuration to be specified with the intended test object.

Technical Specifications
| Reference parameter | Catalogue value |
|---|---|
| Rated voltage range | ±100 to 6000 kV and above, by configuration |
| Rated energy range | 2.5–1200 kJ |
| Stage voltage | ±100 kV or ±200 kV |
| Standard lightning impulse | 1.2/50 µs |
| Switching impulse | 250/2500 µs |
These are catalogue family references. Rated energy, charging voltage, test-object load and the required waveform must be assessed together. Stage voltage is not a capacitance value.

Questions About This Machine
What is the difference between rated energy and stage voltage?
Rated energy is given in kJ; stage voltage is given in kV. They describe different system characteristics and are not interchangeable.
Are lightning and switching impulses identical?
No. The source lists a 1.2/50 µs lightning impulse and a 250/2500 µs switching impulse. State the required waveform and test procedure when enquiring.
