Today (14 July 2020), I am publishing 4 article topics about switchgears testing that I think are useful articles for all friends and colleagues, along with a summary and the names of the authors of the article and article DOI number & date of publish:
Power frequency withstand voltage type testing and FEM analysis of the medium-voltage switchgear busbar compartment
This paper presents the “new” busbar geometry for the existing Medium-Voltage switchgear feeder. The investigated feeder is BVK-A-17,5 manufactured by KONČAR-Electrical Equipment Inc. This feeder uses supporting epoxy resin insulators to support its busbar geometry. In this paper the busbar geometry without supporting insulators is proposed. When dealing with new design of the product the type testing is inevitable. Type test of interest in this paper is “Short-duration power frequency withstand voltage test”. The prototype consisting of two feeders is built, and type tested in the company facilities. New busbar geometry successfully passed the type test. This paper also presents FEM analysis of the type test and compares 3D and 2D model simulation results with the outcome of the real-life test.

Laboratory tests of medium voltage switchgear isolators
This article presents results from laboratory tests of MV switchgear isolators, that were exposed to violent environmental conditions. Tests were carried out on support and bushings isolators. The problem occurred when accumulation of various active gaseous media in the interior of the MV switchgear and in contact with moisture form aggressive substances (i.e. acid). The tests setup with partial discharges detector and results from experiment were presented in the paper.
