| Abstract |
This paper describes the characteristics of a newly suggested arc-inducing driven rod with needles which could effectively spread out both the failure current with power frequency and the lightning current. The structural characteristic of the driven rod was that needles were attached on the surface of the conventional shaped driven rod and the driven rod with needles was installed inside of a copper pipe. As a result of analyzing the characteristics of this suggested driven rod when it was employed as the driven rod of an arrester in distribution system, it was verified that the primary voltage of the arrester was reduced by effectively exhausting the electrical energy since the arc occurred between the needle and the copper pipe. |
