| Abstract |
On January 1, 2021, it was enacted and revised to facilitate the application of the relevant industry in order to meet international standards and improve and supplement the requirements by conducting code changes and technical reviews during the grace period for application of the Korea Electrical Equipment Regulations. Based on this background, 'KEC', the standard for installing electrical equipment in Korea, was developed so that the grounds for many foreign regulations could be identified based on IEC standards similar to those of the domestic electrical environment and applied to domestic sites. The ground resistance and ground resistance were measured and the simulation results were derived and interpreted by applying the KEC grounding method revised through the on-site project. So, we checked how the KEC grounding method was applied in the field and learned the technical characteristics and construction method. |
