Dielectric constant of insulating oil is a significant parameter of the dielectric spectroscopy analysis. The degradation of these properties makes the oil inappropriate to be used as an insulating medium. It is observed from many studies that the dielectric constant of NEOs is greater than that of the MO. This is because of the triglycerides present in the NEOs, which makes the ester oils strong polar dielectric.
