Abstract

This article discusses the application of dielectric frequency response for the analysis of the insulation in MV, HV and EHV instrument transformers. Overall condition assessment of instrument transformers should not be limited to the analysis of the electro-magnetic circuit; it must also include a reliable method to analyse the insulation of instrument transformers.

Keywords

current transformer, potential transformer, dielectric frequency response, frequency domain spectroscopy, diagnostics, standardization
