The standards of demand, diversity and load density are necessary to create the reasonable design method of a transformer capacity that is seldom presented in terms for academic study. At the moment, both legal and institutional standards for such a transformer capacity are insufficient both at home and abroad. This paper shows a reasonable design method that was made by the systematic and statistical way considering actual conditions, such as investigated contract power and peak power for the last 5 years of each customer for 34 apartment customers with design data of electrical installations. The works described in this thesis strongly support more reasonable standards for calculating transformer capacity by correlating the analysis between the maximum utilization factor of a given transformer with those of a transformer capacity whose power consumption has been investigated within apartments. In this dissertation, it is necessary to analyze the key features and general trend from the investigated data. It made an analysis of the feature parameters, such as average, median, maximum, minimum and thus it was carried by the linear and nonlinear regression analysis. |
