Electrical Installation Guide 2015

The international standards set by the IEC are complex and keep evolving; as a result, we all struggle to stay informed. Fortunately, experts in the field from Schneider Electric got together in order to update the Electrical Installation Guide (EIG), a free and complete guide about electrical installations and their standards. This reference work helps you understanding and respecting the IEC standards to be applied in 2015.

Gas insulated VS Air insulated substations

Due to the large power demand brought about by a growing population and a robust industrial sector, there is a need for the power supply company to embrace efficient methods. One of the key areas is substation insulation. There are two primary substation insulation systems in the world, Gas insulated, and Air insulated substations. This article highlights the primary differences between the two.

Top 10 Reasons of Equipment Failure And Overvoltage

Most of the complaints that get registered about the damage of electrical equipment state that, "the equipment failed after power interruption." But what might have caused these power interruptions? Lightening? Voltage swells? Or switching transients? There are many known and unknown reasons. The ones in this article occupies top 10 position.

Electrical Fuses : Their Types & Applications

The basic purpose of the fuse is to protect and is composed of an alloy which has a low melting point. A strip of this fuse is placed in series with the circuit. What is the working principle of it, and what types of fuses does exist? The answer is in this very good article!

Armature reaction in DC Generator

Armature reaction is one of the reasons that causes generated emf in DC Generator to decrease. And this effect is as much important to note as the armature losses and other constant loses like windage and iron losses, because all of them consequently gives us a decreased emf. But compensating winding and commutating poles appreciably decrease this effect and greater part of overall losses in DC Generator is compensated. This article is focused on one particular aspect of DC Generator.

The Electrical Engineering Community FREE Resources

To conclude the year 2015, we want to give you some information about the Electrical Engineering Community available resources. Did you know we had free resources created by the moderator team and some members? If not, check them below:

PowerFacAging calculator

The PFC is a calculation tool we created in 2012. It's focused on Energy savings obtained when installing capacitor banks (and not, as many exist, to calculate the kvar required to improve power factor).

The calculator has been put online since June 2012 and has been used thousands times.

40% of users were surprised by the impact of capacitors aging on cost savings, which highlights the importance of a proper maintenance of capacitor banks to be sure they brings the right level of expected savings on energy costs.

If you want to use the calculator too, click here to start using it!

The Load shedding guide

Four years ago, we proposed you to download a valuable guide (17 pages) about Load-Shedding functions & potential business.

You are an electrician or contractor?

You would like to boost your business by 20% (on the panel board), inresidential & small commercial buildings?

Then you need to download this free guide!

Click here to download your free copy of the Load-Shedding guide!

Electrical Calculation Tools (sharing area)

The Electrical Engineering Community blog has a sharing area created for the members. You all can access the electrical calculation tools shared by each other.

And we are really proud of the result, as we have today more than 80 tools which have been shared by some of you. These tools range from simple calculations (Capacitor bank sizing .) up to complete electrical installation dimensioning!

On the picture, you can see an overview of this sharing page, which contains all the links to access the tools which have already been shared by members of the community.

In order to access these tools a username and password is required which will be sent to you once you share your own electrical calculation tool with the other fellow members.
