Electrical Equipment Protection

As an electrical engineer, Electrical Protection is one of your main concern and also a priority for an effective installation.

Let's focus on 3 articles dealing with protection published in the blog this month...

Read about electrical protection following 3 contexts:

1. Domestic electrical wiring: protection schemes & standards

2. Protection of generators

3. Electrical system protection mechanisms

If you would like to publish an article in the blog just tell us by mail. You can even post directly on the forum!

You can write about whatever you want (debate, tutorial, product review, your observations, your opinion as an engineer or student, etc.).

Thanks in advance for your active contribution to our community,

    Choosing electrical insulator for MV and LV distribution overhead-lines

    Electrical insulator insulates and separates the charged portion of any equipment or machine from the uncharged part.

    Choice of suitable insulators for any power carrier line is a tricky process and should be given proper attention.

    Any comment on how to choose the appropriate electrical insulator?

    Cable sizing: methodology in underground duct banks

    In case of medium and low voltage cables, the terms size and efficiency are related to the minimum cross section that is fully in compliace with sizing criteria.

    In this regard, three criterias must be met for the selection of the appropiate cable cross section in underground duct banks. These criterias fore cable sizing are: Ampacity, Voltage Drop and Short Circuit.

    What do you think of the described methodology for cable sizing?
