Research on Influence of Voltage and Temperature on Frequency Domain Dielectric Spectrum of Drytype Epoxy Resin Impregnated Paper Insulating Bushings

This paper takes the dry-type epoxy resin impregnated paper (RIP) insulating bushings as research object, and builds a test platform of voltage and temperature influence characteristic. How voltage and temperature influence the Frequency Domain Spectroscopy (FDS) characteristics of the bushings was studied, and anti-electromagnetic interference method based on increasing test voltage and temperature correction method of the FDS characteristics based on the Arrhenius equation was proposed. The application in a converter station verifies the effectiveness of the anti-electromagnetic interference method and temperature correction method for the FDS characteristics of the RIP bushings.
