Earth Leakage Circuit Breaker (ELCB)

October 12th, 2017 | Make a comment | Posted in Electrical distribution

Hi community! We’ve already dealt with Earth Leakage Circuit Breakers 3 years ago, but today here’s a new article from our fellow member Manish about this topic, which is refreshing. Hope it will help! If you have questions, leave a comment.

Introduction

In my last article I told you about Residual Current Circuit Breaker (RCCB). Today we will take a look at another important type of circuit breaker called – Earth Leakage Circuit Breaker (ELCB). An ELCB is another different class of Circuit Breakers with a specific function.

FACTs Controllers (back to basics)

October 9th, 2017 | Make a comment | Posted in Power quality

We electrical engineers have our own glossary so when we see the word FACTS we know that it doesn’t mean the things that are indisputable, but Flexible Alternating Current Transmission Systems.

My name is Yasser and I want to go back to the basics with the Flexible Alternating Current Transmission System. Enjoy!

Why FACTS controllers?

The evolution in power electronics regarding high current and voltage is very obvious which reduced the cost of energy in many applications by many ways including transmission of current over very long distances and reduction of the cost in renewable energy applications.

Testing faults in cables

October 5th, 2017 | 1 Comment | Posted in Electrical distribution

megaphone-blue Electrical cable faults are some of the major causes of interruptions to the smooth flow of power to the load and can also become a safety or fire hazard.

Here’s an article proposed by A.N. who sent us a lot of essays.

Introduction

The effect of a fault cable depends on the type and extent of the fault. Some cable faults reduce the amount of power reaching the load, while an open cable will completely cut off the power to the loads in the affected section.

system stability curve

One of the most important features of an electrical power system is stability. An electrical power system must be stable within the predefined limits against different types of disturbances.

That is the topic that Yasser (one of the members) chose to deal with. If you want to be published in the blog too, send us a mail
