It's about fixing a short in a power transmission line. Sounds simple, right? It involves liquid nitrogen and hundreds of people with possibility of explosions or huge oil spills. That's right, the line is suspended in pressurized oil! It goes on…
I tried to find a good pull quote, and it's basically all mind-blowing pull quotes. But here:
"Every vault also has a nipple which allows sampling of the pipe oil. They said you withdraw the oil through a thick membrane with a syringe (?). This happens monthly on all feeders in the LA area. The samples are analyzed downtown by a staff of chemists who can relate the presence of things like acetylene, butane, and benzene in the oil to arcing, coronas, and so forth. Apparently the oil chemistry is a very good indicator of the health of the segments."
