Editorial
This amazing flexibility gives tremendous power to the protection, automation and control specialists, but like everything else in life it comes with a price - you must do your homework. We have to ask a lot of questions and answer them during the system design process. When the topic is IEC 61850 based centralized substation protection and control systems, the first question is “What d... More
