Different electrical equipment and test standards may require different impulse waveforms. A configurable lightning impulse test system helps manufacturers and laboratories evaluate insulation performance under specified transient voltage conditions.
Depending on the system design, the generator can support standard lightning impulse full waves, chopped lightning impulse waves and switching impulse waves. Waveform generation, measurement and acceptance criteria should be matched to the applicable test standard and the characteristics of the test object.
Transformer insulation tests, GIS and switchgear testing, cable insulation evaluation, insulator testing and laboratory type tests.
A full-wave test applies a specified lightning impulse waveform. A chopped-wave test introduces a controlled voltage collapse at a defined point to evaluate the equipment under a different impulse stress condition.
Some systems can support both, but the available waveforms depend on generator design, voltage rating, energy rating and the required additional components.
Using an appropriate high-voltage measuring system, voltage divider and acquisition equipment, with evaluation against the applicable standard.
Yes. Provide the test standard, required waveform parameters and test object so the configuration can be reviewed before quotation.
