Abstract :
Based on the dielectric loss factor (tan delta) test results of transformer bushings in the artificial climate chamber, this paper analyzes the effect of environment factors on the tan delta of capacitive equipment. And the grey corelation analysis model of the environment factors effect on the tan delta is established. The influence of temperature, humidity and contamination on the tan delta are evidence when there is no shielding ring. When the shielding ring is applied, the influence of temperature is more than the influence of humidity and contamination.
