#2Looks like a transformer blew up. Happens all the time.
Funny how the best footage on TV news comes from random cell phones.

you do NOT want to be anywhere near old transformer oil, burning or otherwise

Are you confident it’s not? I’m not confident anymore.

#7LOL. The whole Twitter thread is news agencies asking if they can use the video, and regular people telling the OP to "screw credit, get paid!"

#8Looks like a transformer blew up. Happens all the time. Funny how the best footage on TV news comes from random cell phones.
From the photos this looks like it might be an isophase bus GSU transformer, which is responsible for stepping up generation voltages for one or more generation units to substation voltages. These transformers are large, very expensive, very long-lead custom designs and consequently are closely monitored for temperature rise, hydrocarbon gas discharge, and gas pressure, in addition to various other electrical relay protection schemes acting on the faster electrical damage hazards. They are usually very well protected against all possible major equipment failures. The fact that this happened is an enormous screwup, it's not even within a few orders of magnitude of the power pole transformer that blows up during a lightning storm or similar.

Anyone else feeling like mishaps involving backbone infrastructure and logistics centers are getting a bit common?

Seems like it but might be due to poor maintenance schedules over the last two years catching up to us rather than sabotage or the like.
