摘要

This paper presents a 24 factorial design to analyze the joint effect of loading, cooling characteristics, ambient temperature, and Oil Time Constant (OTC) on transformer Loss of Life (LOL). Transformer LOL is calculated for 16 combinations of factor levels. Residential load profile obtained from a utility is used to precisely model the loading factor. Design-Expert® Software Version 9 is used to statistically analyze the joint effect of factors. Results show the significance and contribution of factors and their interactions to distribution transformer loss of life.
