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