Easy Evaluation of Streamer Discharge Criteria

G. Eriksson[1]
[1]ABB, Corporate Research, Västerås, Sweden

An easily implemented method is devised, where analytical criteria for the occurrence of streamer discharges in strong electric fields are evaluated. This is highly useful when designing high voltage power transmission systems and components where the insulation is provided by a gas, e.g. air or SF6.
