| Abstract |
This paper describes the influence of the bridge formed between electrodes by electrolyte for tracking process. Electrolytes is made by IEC(International Electrotechnical Commission) 60589, NaCl added to deionized water as each 1, 3, 5[wt%]. The used test equipment is made according to KS(Korean Industrial Standard) C IEC 60112. It is investigated voltage, current, value of resistance and thermal image when bridge formed between electrodes on tracking process As a result, as conductivity of electrolyte gets bigger as Joule’s heat on bridge also gets bigger. But It is not over electrolyte’s boiling point clue to evaporation heat of electrolyte. However as conductivity of electrolyte gets bigger as the necessary time of dry band gets shorter. So dry band is existed more long time between ahead of droplet to next droplet and discharge chance at dry band gets much. Therefore tracking process gets faster. |
