Gaussian Noise Representing Lightning and Switching signal

Does any one has a script or information that shows the representation of lightning signal and it corruption of fault signal

[Walter Roberson]

When I look at the diagram at https://www.voltimum.com.au/articles/basic-surge-protection-principles it appears to me that you cannot model lightning as a gaussian -- the peak is too high and fast relative to the rest of the signal.

Taking the sum of two gaussians might be a good enough approximation, provided that the second one has a high amplitude and high phase.

Walter, another question on a different topic. I want to tab standard deviation and variance on the feature representation but only entropy is featured out. Could you please look into it.
