I would like to know at what percentage of theoretical spark energy does sparks occur in actual conditions and how much it does vary. Does the spark energy variation follow a normal distribution?
Dear Jithin,
The following manuscript may be helpful. Those manuscripts are not dealing with measuring the spark energy; rather dealing with influence of spark energy. If you will need it, you can consider

The spark energy can be calculated relatively easily from the i (t) and u (t). To analyze which discharges are sparks and which are not called them some papers. If, for a high number of discharges, they apply this via the spark energy, then it seems to me very unlikely that this will be a normal or Gaussian distribution. There is not even a correlation about the fact that the same discharge energy must always be a spark. Since this distinction may include e.g. (Spark, arc, short circuit), the discharge energy is only a conditional analysis factor.
It is much more interesting, but it is very expensive to determine the correct distribution of the spark energy for a given electrode arrangement on the cathode case, the anode case and the discharge channel.
Thanks for the answers Muthuramalingam, Kai Owald and H P Schulze.
I found them very helpful.
