| Abstract: | The method of processing several discharge voltages＇ data using Weibull probability plot model is presented, According to the standand that probability of insulator string tolerance and arc - protection hardware gap breakdown achieve 99. 85% to design the gap distance. The method has the eharaeteristics of accuracy and easy to operate. By test results, the best gap distance of arc - protection hardware used for 10 kV overhead insulation lines and P15 pin insulators is 9. 5 cm. The result provides methods and ex- periment basis for the application of arc - protection hardware at high altitude areas. |
