Power Quality

The "Power Quality" category is one of the most important of our blog because as engineers you always need to improve and optimize your electrical installations.

This is why we propose you to check 3 of the latest articles published in this area so that you can learn more and more about power quality ; or simply check infomation as a reminder.

1. Power system: mid and long term stability

2. Requirements for a good grounding system (400 kV power line)

3. 3 Different ways to improve Power Factor

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,

These past weeks, some topics in the forum remained without answer. Maybe you could help the members to solve their problem.

Don't forget: it takes 5 minutes to do it and the person asking may become the one to answer YOUR questions in the future!

1. LED Control Circuit project; few advices needed!

2. How to set parameters and safety of a 1250amp Vacuum circuit-breaker?

3. How to deal with Electronic power system issues with cars?

FACTs Controllers (back to basics)

We electrical engineers have our own glossary so when we see the word FACTS we know that it doesn't refer to something that is indisputable, but to Flexible Alternating Current Transmission Systems.

Let's go back to the basics with the Flexible Alternating Current Transmission System!

Did you find this back to basics article about FACTs helpful?

Earth Leakage Circuit Breaker (ELCB)

An Earth Leakage Circuit Breaker ELCB is another different class of Circuit Breakers with a specific function. It's a safety device used in Electrical circuits with high Earth impedance to prevent the risk of Electrical shock.

An ELCB is a voltage operated device. It detects small stray voltages across metal enclosures of electrical installations and interrupts the circuit if the voltage level exceeds danger threshold.

What do you think about this review of ELCBs?

Residual Current Device & Residual Current Circuit Breaker

Electrical Installations for Buildings Standard IEC 60364 asks for installation of Residual Current Devices in specific parts of the circuit like power sockets and circuits powering electrical equipment operating in humid/wet environments like bathrooms and kitchens.

These Residual Current Device (RCD) or Residual Current Circuit Breaker (RCCB) monitors the current balance between the hot and the neutral wires and breaks the circuit when there is a difference in current flowing through them.

What is Residual Current Device & Residual Current Circuit Breaker and where to use it? Read now!
