Reverse current is another security risk. In normal conditions, distribution from power source is passed by busbar system to the devices with interconnection with voltage regulators and control units. In case of malfunction there is possibility for reverse current to occur.

Let’s find out more about it thanks to this article that our member Mile kindly sent us.

When we have reverse current situation, something is wrong with DC generator. So, generator fails and cannot provide electrical power and starts consuming current instead of providing it. Obviously, when this situation happens, generator is becoming a load to electrical distribution.

Basically, there are two methods for protection, reverse current cut-out relay and reverse current circuit breaker.

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.

Underground installations are made to replace overhead cables with underground cables. They offer good solution to limit blackouts and outages during wind thunderstorms. They are also very appealing compared to overhead lines which tend to overwhelm the sky.
