Lightning impulse high voltage test

  1. Dec 17, 2013 #1
    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 ?

    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...
