Improved Insulation Design Scheme for 145kv Current Transformer with the Help of Electric Field Analysis through Finite Element Method

Abstract
This paper proposes a new Capacitive graded bushing configuration for 145kV Live Tank Current Transformer which has lowest possible maximum electrical stress in it. Capacitive graded bushing breakdown is one of the major reasons of Current Transformer failures (In-service and at test bead). Since this bushing is heart of the current transformers so it is necessary to design it carefully and the electric stress distribution in capacitive graded bushing is primarily dependent on the geometry and dielectric properties of material. The main motive is to obtain the better design of a capacitive graded bushing which will have reduced electric stress as compared with the existing design. Capacitive graded bushing contains concentric aluminum foils which are isolated from each other by Oil Impregnated Paper (OIP). The partial capacitances (Combination of Series and Parallel) between these can be modified by adjusting the number of foils, its diameter, width and foil staggering also the thickness of dielectric material between foils. This stated grading configuration’s stress level is under the limit considering all practical conditions, taking the various literature, IEEE transactions and practical results as benchmark. This paper reveals the configuration which gives improved and optimal electric stress distribution in the designed bushing configuration and which ultimately reduces the oil volume content, cost of active part insulation and the porcelain housing as a whole product.
