August 2003 blackout. Which was started by a tree falling on some
power lines....

Maybe he meant a (small) 48 kvA transformer?

the 48kv transformer

Hate to spoil the impact of it all, but they dont run 48,000 volt
lines in
residential areas. In fact most lines are 38,500 Volts to each
other and
19,200 Volts to ground on the real hot services you see along the
highway
or
electrical "right of ways" (big power towers)
In your neighborhood it's usually 4800-6000 Volts on the primary.
If your
WAY out there, possibly 16KV for rural customers.
Street lighting primaries are 5,000Volts/6Amp regulated loops.
It's still enough to make your tree go BANG...just not as hot as
you think
they are.

AEP (ex CSOEC) runs 48kv for rural distribution. A few years
ago they came out, replaced all the transformers and insulators,
doubling the voltage, rather than replacing the wires. Anyway
that's what the guys said who work on lines; as well as a couple
placards warning of 38kv(?) lines crossing 48kv lines, where my system
intersects another. Placard now gone.
