Medium voltage DC configuration and control

September 4th, 2017 | Make a comment | Posted in Electrical distribution

The distribution is the final stage of carrying electricity from the transmission system to consumers. The distribution substations are connected with transmission lines and the voltage reduced to medium voltage through the transmission systems as shown in Fig1.

New article by Yasser, one of our members who kindly sent us this article. Enjoy!

Throughout the last 4 decades, switchgears development was just obvious at a glance. This electrical device which we use when we want to connect, disconnect, regulate or control the flow of electricity in a power system, is a vital part of any medium voltage power stations.

That’s why studying the faults and failures reported in switchgears is very important and finding solutions is a main concern for all the companies that produce and maintain switchgears to insure reliability and stability of the power systems.
