A New Power Line Carrier Book is Now Available at www.plcexperts.net
Jeffrey Brown reached out to help announce his new book, Power Line Carriers – Simplified: A Field Engineer’s Perspective [pullquote align=”normal” cite=”Jeffrey Brown – www.plcexperts.net”]I would like to Introduce your First and Last Book on Power Line Carriers. Everything a Field Engineer needs to Know when it comes to protecting
High Impedance Busbar Differential Protection
We covered the basic operating principles of high impedance busbar differential protection in our previous post, I Want to Know How a High Impedance Differential Scheme Works. You should read that post first before we dig deep into the calculations and considerations that explain how high impedance busbar differential schemes function.
I Want to Know How a High Impedance Differential Scheme Works
We received this question from the Ask Chris form at relaytraining.com. Follow this link to ask your own question and it might appear in a future blog post. High Impedance Differential Scheme Testing High impedance differential relays are some of the easiest relays to test. Isolate the relay from the
What is DC Offset? Ask Chris
I was recently asked about DC Offset during a paper I presented at the 2015 Hands-On Relay School and struggled with an answer because I know what it looks like and I know it exists, but I’ve never heard an explanation that made sense to me. The answer you usually
Ask Chris: What is the best path for high voltage electrical employment as a relay technician?
Here is a question submitted to the Ask Chris section of the RelayTraining.com website about the best path for electrical employment. I have just recently completed an IBEW apprenticeship and tested out as a Journeyman Lineman. I am currently working in construction. I have a question regarding a career goal. To
Please Explain the Principle of Weak InFeed Echo Permissive Over Reach Transfer Trip Schemes?
Rahim submitted this question to the Ask Chris section of the RelayTraining.com website. Most line distance protection schemes assume that the system will always be able to supply enough amps to make the relays trip. However, there are many scenarios on transmission systems across the world where you could have
