Among the list of Electrical Design documents, Electrical load list is primarily the most important document. The load list, also known as the load schedule, is defined as a document that calculates an approximation of active, reactive and apparent power of instantaneous electrical loads that are being used in a project [1].

As only few milliamperes can kill a human in a part of second, safety always is the big concern for electrical engineers and protection systems designing gets much more attention.

This is the topic our fellow electrical engineer Yasser chose to discuss today. As a reminder, you too can be published in this blog, just send a mail to the team!

Protection and fuses

Usually the word protection in electrical engineers’ glossary is associated with Circuit Breakers (CBs) and Fuses. These devices are the muscles of protection systems which isolate and protect them from different kinds of faults and/or abnormal conditions.

Your fellow electrical engineer Jesús Pérez Díaz is back with a great new article featuring a video tutorial (ETAP software). Enjoy!

LV MOTOR PROTECTIVE DEVICE

250 hp WEG motor / HMCP Cuttler Hammer / Overload Relay Schneider Electric

Hello everyone! In this article I want to show you how to determine the protective device settings of a typical and simple protection scheme usually applied to low voltage motors, considering the electrical protection basis and using ETAP (Electrical Transient and Analysis Program)to build the time-current curve.

megaphone-darkbluePreparing a load schedule helps in determining the amount of power required for an installation. This information is then used by electrical engineers to properly size conductors, conduits and determine the proper overload and other protection and control systems.

Let your fellow member A.N tell you about it and don’t hesitate to send us a mail if you want to be published in the blog too!

Read this short essay by one of the electrical engineer following this blog. Will Daylight Saving Time (DST) be finished soon? Here is his oopinion on the subject. You too tell us what you think in the comment area below.

Lighting new generation

Many people believe that with new improvement in low energy light producing (LEDs), the Daylight Saving Time (DST) would not be applied soon and would become an old-fashioned thing.
