The corrosion process in devices and equipment of switchgears strongly depends on environmental parameters. In some cases, degradation of copper conductors and other insecure elements is impermissible intense and provides the increase of failure and exploitation costs of such devices. In the paper, an author's system for measurement and registration of chosen environmental parameters is presented...
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...
