| Abstract |
The Korea Electro-Technical Code (KEC) was enacted in March 2018 to meet international standards and develop the country's power industry, and will be implemented in January 2021. In KEC, the protection coordination between the cable and protection devices was to be in accordance with KS C IEC 60364. In this paper, I propose the design of protection coordination between cable and protection devices applying KS C IEC 60364 to draw out the problems of the design method based on the Technical Regulation in Electricity Business Act. In addition, the application method of demand factor for economical low-voltage wiring design was proposed. For the verification of the proposed design method, the design of low-voltage wiring in a certain apartment complex was modeled, and the analysis applied with the Technical Regulation in Electricity Business Act and KS C IEC 60364 was performed.
Finally, it is expected that this paper is utilized as a reference for designing economical and reasonable low-voltage wiring. |
