Abstract (en)

[origin: EP0911804A2] The method involves determining the discharge curve of the spark discharge system and comparing it with a nominal curve, and automatically correcting for deviations in the separation of the spark gap electrodes. The correction may involve ensuring that the discharge occurs at maximum charge of a high voltage capacitor (12).
