These waveforms are available in chart form from HV Technologies, Inc. at emcsales@hvtechnologies.com. There is additional information in that chart as well.

One way I've used equations like these was to derive a text file of amplitude values and times, import that table into a Multisim SPICE arbitrary waveform generator and then use that generator to drive a circuit of interest to examine what would happen.

The other way was to include such waveform equations in recursive differential equations analyses. See:

In your opinion, do "Porcupine" devices disipate lightning feelers or is that just wishful thinking?

John Dunn

From directi information, Terry, I have no idea. My gut level intuition would be "no" however, if I understand the device correctly. All kinds of sharp points would each be a concentration site for e-field.

Terry - in my experience, streamer inhibition is possible. I would recommend you this URL: http://www.lightningelectrotechnologies.com/GHX/icon-VideoSection.png
The inventor talks about the Glow Mode Corona and Streamer Mode Corona which would make the Porcupine devices not effective for streamer inhibition, however the inventor proposes and displays a technology that definitely delivers "Streamer Inhibition".
