Hello eveybody, it’s Yasser and I’m back with a guest post. I have questions for you:

Have you ever been angry for losing some data while working on your PC and a power outage occurs? Have you ever imagined what will happen if some main servers of the internet had power outage?

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.

Again, one of you sent us an article for it to be published on the blog. We wanted to let you know that we appreciate your committement to this community.

We’ve received this essay from Yasser, an electrical engineer from Egypt. He’s interested in all electrical engineering subject and Business related subjects and if you want to be published on the blog, you can of course send us a mail. We agree to post any type of writing!


It’s clear that one of the most common electric businesses is electric distribution for residential, commercial and industrial buildings. And as a rule of thumb all residential buildings have three-phase wye supply and also nearly most of small commercial and industrial facilities. Speaking about wye connection we expect that all three phases have about the same amount of current and the neutral have a very little current, this case is called a balanced system.
