AREVA NPAG PDF

Image reproduced from 'Network Protection and Automation Guide, by Areva This morning I was explaining how differential protection works to a junior engineer. I was immediately confronted with Marz and Price, circulating current systems, balanced voltage systems, high impedance series connected relays, illustrations like the one shown, etc. A time when if you mentioned differential protection to an electrical engineer, they would turn and run in the opposite direction. I think this is a pretty clear example of how changes in technology have vastly simplified something. Not only has it simplified the application of differential protection, it also comes with a host of advancements — being able to use CTs manufactured to different specifications as an example. Numerical relays and optical links may not be the answer to every situation, but I think they make life easier for most of us.

Steven has over twenty five years experience working on some of the largest construction projects. He has a deep technical understanding of electrical engineering and is keen to share this knowledge. About the author. Lamps are the essential part of any luminaire. These are the light generating components.

Since the advent of electrical lighting in the middle of the Reading is a bit of a hobby of mine and I"ve done a few off-topic posts in the past on this. Rather than continue doing the occasional post I thought One of the fundamental requirements of an alternating current distribution systems it to have the ability to change the magnitude of voltages.

It is more Our cable sizing tool is one of the more popular tools on the site. IEC 'Protection against lightning' requires a risk assessment be carried out to determine the characteristics of any lightning protection system Multimeters are undoubtedly the most common item of electrical test equipment in use. Often it is the first piece of equipment people will turn to when The intention Depending where in the world you work, you are likely following one of two standards International Electrotechnical Commission IEC National The robot folding towels post below was interesting enough at the time to post a link.

Differential protection, the good old days

Since , the Network Protection and Automation Guide formerly the Protective Relays Application Guide has been the definitive reference textbook for protection engineers and technicians. New chapters treat topics such as system integrity protection and remedial action schemes, phasor measurements and wide area schemes. Advancements in protection and control application engineering have assisted the authors in exploring and integrating the new techniques and philosophies in this edition, whilst retaining vendor- independence — as we continue to deliver the genuine, impartial, reference textbook. This course, by the ingenuity and dedication of the trainers, is vibrant and evolving. Beginners and experts alike will each feel satisfied in their search for relaying , measurement , communication and control knowledge. Thank you for posting this greatly sought out book and articles from time to time that help us electrical engineers keep up to date. Hello Edvard!
