Lightning Impulse Test System for High Voltage Cable and Insulation Testing, Impulse Voltage Generator for Power Cable Type and Qualification Tests

The Lightning Impulse Test System for High Voltage Cable Testing provides controlled impulse voltage for evaluating the transient insulation withstand capability of high-voltage cables and cable accessories.

Impulse testing is used across cable systems to evaluate performance under transient overvoltage conditions. IEEE also identifies impulse testing applications for high-voltage cable systems.

High-voltage cables can present substantial capacitive loads. Therefore, the generator must be selected according to the cable length, capacitance and required test voltage.

Cable impulse testing may require considerable physical space. The test hall layout, clearances, grounding and cable arrangement should be considered during system design.

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.
