Abstract
Polish power industry is characterized by outdated elements and in poor technical condition. This applies mainly to overhead lines operating at medium and high voltage (MV and HV) levels. Moreover, the Energy Regulatory Office (ERO) requires the Distribution System Operators to supply electricity with specified parameters, ensuring uninterrupted electricity supply to end users. Failure to meet these conditions results in specific financial penalties. In connection with with the above, there is a strong need to upgrade the existing electricity grids using modern equipment. The article presents an innovative, original research position based on the so-called dismountable vacuum chamber, which allows to conduct research on improving the performance of modern switching equipment used in Smart Grid networks. The article also presents the results of the electric strength tests of the inter-contact break in order to confirm the correctness of operation of the described test stand.
