It’s always a pleasure to receive an article from Muhammad, one of the senior members of this Electrical Engineergin Community Blog. Let him and his 20 years of experience telling you about faulty systems and read his tips on how to detect them.

If just like him you want to send us quality articles, we’ll be glad to publish them on the blog! It’s easy, just send us a mail so that we can discuss. For now, enjoy this great article.

Faulty System: Engineers are detectives

An engineer is always a bit of a detective when he or she is trouble-shooting a faulty system. Different faults can have different levels of complexity. How difficult is a fault to trace? That depends on the qualification and expertise of the engineer who is trying to diagnose and repair, and the nature of the fault.

Electrical Protection Systems: Design & Installation

April 9th, 2018 | 2 Comments | Posted in Electrical Safety

megaphone-blueYasser sent us an article about electrical protection systems and chose to focus on design and installation.
We thank him for bringing more knowledge for our electrical engineering community.

If you want to do the same, please send us your articles by mail.

What is a power protection system?

A system which is responsible for protecting electrical systems from faults by isolating the faulty part from the rest of the system, so power is not disconnected from healthy parts and this increases system reliability and efficiency.

Distance Protection Schemes & Relay Settings applied to Multiterminal Lines

April 5th, 2018 | 2 Comments | Posted in Electrical Safety

Carlos V. is an electrical power systems protection expert. Let him tell you more about distance protection schemes and relay settings applied to multiterminal lines. A second part of this article will be published soon.

Introduction

Multiterminal lines tipically have at least a weak source in one of their terminals as it is shown in figure 1. This condition could negatively affect the performance of the protection systemduring the ocurrence of a faultalong the lines.

It is posible that the weak source terminal might not be able to provide enough current to the fault for the operation of theprotection relay locatedat this terminal, due to the high impedance of the weak source.
