September 2019 Issue
I remember when we installed a synchrophasors measurement unit at New York State Electric and Gas in 1993 as part of a New York State project to gain some experience and see what we can do with this technology. So, it has been more than a quarter of a century of synchrophasors availability and things have changed a lot, while at the same time in many places staying very much the same. What... More

IEC 61850 Update

Why do top-down engineering?

When you read the title of the column, you probably recognize it. You are right - my last column already had that title. The reason I repeat it? Quite simple - I have something to add based on recent experience; I have more to say and the space in the last column was not enough. I mentioned a few arguments for top down engineering and vendor independent design in my last column. Another req... More
