Lightning impulse high voltage test

Click For Summary
SUMMARY

The discussion centers on the analysis of two lightning impulse waveforms, specifically focusing on their differences and characteristics. The first waveform is identified as a "Combo Wave," commonly used in surge testing as per the EN 61000-4-5 standard, which simulates lightning strikes affecting AC mains supply lines. The second waveform remains unidentified, prompting further inquiry into its origin and significance. Participants seek references for a deeper understanding of these waveforms.

PREREQUISITES
  • Understanding of lightning impulse waveforms
  • Familiarity with surge testing standards, specifically EN 61000-4-5
  • Basic knowledge of electrical engineering concepts
  • Experience with waveform analysis tools
NEXT STEPS
  • Research the characteristics of "Combo Wave" waveforms in surge testing
  • Explore the EN 61000-4-5 standard for surge immunity testing
  • Investigate other types of lightning impulse waveforms and their applications
  • Learn about waveform analysis software and tools for electrical testing
USEFUL FOR

Electrical engineers, surge testing professionals, and anyone involved in equipment protection against lightning strikes will benefit from this discussion.

Hello, I am posting this here becase this is not a homework, it;s just something I need to know.
Please tell me what these two waveforms mean? I know that they're both lightning impulse waveform but what is the difference between those two, what gives them their shapes?

where did you get these waveform images from?
have you got some references ?

cheers

The first looks like a standard "Combo Wave" waveform used in Surge testing (which simulates lightning strikes to AC Mains supply lines leading to equipment). The standard test is EN 61000-4-5. I don't recognize the 2nd waveform...
