The scale of the power system has been expanding year by year, and the society’s demand for power system equipment has also increased sharply. Therefore, the assessment of the life of power system equipment is of great significance to improving the safe, reliable, economical and efficient operation of the power grid. This article will use the Pearson product moment correlation coefficient to evaluate the factors that affect the life of transformer equipment, and explore the correlation between transformer life and installation location, voltage level, cooling mode and other influencing factors to explore the impact of these attributes on transformer life. To provide data support for improving the precision investment level of equipment, and to provide guidance and suggestions for the procurement of power grid enterprises.
