Sažetak
The dielectric frequency response of insulation in power system apparatus is influenced by frequency and temperature [1]. Specifically, temperature is governed by a parameter known as activation energy. This article explores the significance of activation energy in estimating the power factor of dielectric insulation over a range of temperatures and frequencies when using the Arrhenius equation. Several case studies with empirical data are presented to support this investigation.
