This was interesting. A 500 kV substation. Everything overhead is humming and buzzing, 24 hours a day. Only our little section of the substation is powered off, the rest is still working. We installed some equipment in an outdoor cabinet, and also in a rack indoors. We’re doing a bit of a joint demonstration of digital substation technology.
One of the challenging things about this kind of work is that the guys start soooo early. They generally arrive at 5:30 AM. We’d show up 6:30 or 7 AM, just as the sun was coming up. I understand why they do it, of course – there’s no shade out there, and the sun is unrelenting & hot! Hard to believe it until you feel it!
