megaphone1Have you ever been in a mall and noticed some lights went off for a while and then came back?! Have you asked yourself why didn’t them just turn off?!

The answer is the emergency electrical system, so in this article Yasser your fellow electrical engineer will discuss briefly some considerations about emergency systems.

One of the most important things to consider when selecting an insulator or type of insulation for a transformer is to consider the environmental effects, particularly on air and SF6 gas.

That is why we must understand how the gas breakdown is modified when applying different environmental conditions.

Here is another article by Carlos an electrical engineer who have already published an article about gas breakdown theory few days ago.

Gas Breakdown Theory

July 12th, 2018 | Make a comment | Posted in Others

megaphone-darkblueIn order to understand the theory behind the formation of electrical failures throughout the air and to better understand the reasons behind insulation failure, we must go deep into the theories of gas breakdown.

That’s what Carlos wants to share with you all today. He is a consultant for power systems installations and we’re happy to publish his essay. Enjoy!

Current protection

Current protection schemes are integrated into power system designs to protect the power system components from the excessive withdrawal of current and short-circuit currents. Excessive overcurrents could occur on many different power system components such as motors causing hazards if not cleared within the safe time frame.
