접지품질 개선을 위한 접지저항 최적화 및 접지충진제의 전기적 특성 연구
Optimization of the Earthing Resistance and Research on the Electrical Characteristics of New Catalyst for the Quality Earthing
초록
시설물이나 장비로 surge wave가 유입되는 것을 방지하기 위해서는 접지시스템의 접지저항을 수
In earthing technologies, the intrusion of the surge wave can be protected when the earthing resistance is as low as several ohms. However, the cost fer realizing such a low resistance is quite high. Therefore it is important to determine appropriate target value of the earthing resistance to install cost-effective grounding system. In this work, we have proposed an optimization method of the earthing resistance according to the various environmental parameters by using a numerical simulator We have also developed new catalyst composed of water-soluble alkaline elements and activated carbon and investigated its electrical characteristics for enhancement of the earthing qualities.
