HV instrument transformer condition assessment
Diego Robalino
; Megger
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.
