The Analysis of Dielectric Loss Overproof of Dry-type Current Transformer

Dry-type current transformer is widely used in the power grid of 110 kV, this paper mainly introduces the structure and characteristics of dry-type current transformer, analysis the physical meaning and influence of dielectric loss. According to the experimental data and theoretical analysis and after experimental verification, we eventually get the causes of the dielectric loss exceed the standard of dry-type current transformer. We will provide effective cases for the experimental analysis of dry-type current transformer.
