Studies on Ageing Status of Epoxy Nano-Composites for Dry-Type Insulation using Electric Modulus

Abstract

This paper describes the ageing status of epoxy nano-composites based on frequency domain analysis. Frequency domain spectroscopy (FDS) analysis is a non-invasive technique to identify the condition of the insulation. Electric modulus and dissipation factor (tanδ) are the popular frequency domain spectroscopies for condition monitoring of dielectric insulation. An attempt is made to study the ageing (made by accelerated thermal heating) status using electric modulus (EM) and tanδ spectroscopy.
