Customer Pain Points
Cable Capacitance
High-voltage cables can present substantial capacitive loads. Therefore, the generator must be selected according to the cable length, capacitance and required test voltage.
Laboratory Configuration
Cable impulse testing may require considerable physical space. The test hall layout, clearances, grounding and cable arrangement should be considered during system design.
FAQ
Q: Can you test long high-voltage cables?
A: The system can be engineered according to the cable length, capacitance, test voltage and applicable standard.
Q: Can cable accessories also be tested?
A: Yes. Cable joints, terminations and related components can be tested when the system is configured appropriately.
