System VI Switchgear is available through 38 kV, 630 A continuous and load dropping, and up to 25 kA RMS symmetrical short-circuit. It includes motor-operated load-interrupter switches plus a Micro-AT ® Source-Transfer Control or a 6802 Automatic Switch Control. However, for practical and economic reasons, most medium voltage networks are limited to 36 kV. Connecting an installation to a medium voltage utility network typically requires a dedicated substation, known as the. ents), and the electrical equipment, formed by the internal connections and by the incoming and outgoing termina is regard, there has been an evolution which has resulted in the replacement of the previous Standard IEC 60439 with the present Stand rd IEC 61439. In particular, at international. 11 kV', the Ger-man Association of Energy and Water Industries (BDEW), the German Association of the Energy and Power Supply Industry (VIK), the German Electrical and Electronic Manu-facturers' Association (ZVEI) and Solvay Fluor GmbH. Switchgear and electrical equipment are important com-ponents.
