A Comparative Study of Domestic and U.S. Standards for Load Equipment Capacity and Demand Factor Application in Power Transformer Capacity Estimation

In This study examines the estimation values and demand factors for load equipment, which are crucial for transformer sizing, by analyzing the standards applied in Korea and the United States. In Korea, these matters are subject to review by design enginers. Therefore, this study reviews the application, particularly focusing on the application methods for load equipment capacity estimation data and demand factor information in the NEC and IEEE standards. This study examines the standards of Korea and the United States, respectively. This study hope to contribute to the caculation of electrical load capacity and the application of demand factors in the future.
