Maybe he meant a (small) 48 kvA transformer?

The neighbor's power pole fuse blowing out, which I gather it does
when the black locust tree under it grows enough and breezes into
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.
