“…To control the electric field along the surface of a composite insulator, it is necessary to keep the maximum electric field values below the critical value. This is important to protect insulator from corona activity [30]. Thus the E-field distribution along the whole composite insulators is improved and the installation of optimized CR leads to uniform voltage distribution.…”

This paper reports on a new approach for optimal design of corona rings on composite insulator. Finite element method combined with the experimental design methodology and Bat optimization method were used in order to minimize the maximum E-field along the insulator length, with the objective of increasing its long-term performance. Corona ring height (H), radius (R) and tube diameter (Dr) are the most important parameters in the design corona rings. They have been evaluated using different techniques and their optimization was achieved by minimizing the objective function using Bat algorithm which is one of the most recently developed nature-inspired optimization approaches. Simulation studies cover potential and electrical field distributions using COMSOL 4.3, which uses a numerical analysis technique based on Finite Element Method (FEM) were done. Reported results show that the optimized corona ring decreases significantly the electric field near its end fittings. That is, potential distribution will be more uniform with the presence of the optimized corona ring. By installing corona ring, the electric field improves about 58.6% compared with the threshold value. The results show that optimization using Bat algorithm as new methodology is efficient for designing corona rings on transmission line composite insulators and it presents more accurate result in finding the best solutions for corona discharges problems.

“…These devices minimize the probability of failure caused by abnormal situations such as dielectric breakdown, arcing, electrical discharge, etc. [1][2][3][4]. Metal-enclosed switchgear is a typical electrical system exposed to this type of failure in the electric power system [5] and in order to protect the insulator-metal junctions, electric field grading devices can be used [6,7].…”

Electric field grading devices have great importance for both the electric power transmission and distribution systems. This paper presents an improved electric field grading device used in the medium voltage metal-enclosed switchgear. The solutions have been carried out by using Ansys Maxwell 3D software. The structure of two electrodes designed as cylindrical and elliptical have been compared to determine the electric field grading device to be used in practice. The transient and steady-state analyses have been performed in both designs. The field grading device manufactured for the metal-enclosed switchgear has been tested according to IEC standards in a high voltage laboratory environment. This study revealed that the newly designed field-grading device can be used in the metal-enclosed switchgear more safely. It also encourages researchers to optimize the electric field distribution using different geometric structures and to create running conditions in smaller indoor environments.
