Jonathan,
Thanks, that's the unit. It was added sometime in the last three years, (I wonder when) here is a picture from before:
That is one sad looking pole and transformer. The utility around here would have replaced at least the pole a long time ago.
Then again, it appears you live in a mighty dry climate, so an old, weathered pole is likely to still have plenty of life. Around here in the Pacific Northwest, once the volatiles disappear from the creosote and the pole starts cracking and checking, it will lose structural integrity rather quickly. The
local utility regularly inspects EVERY one of the 59,352 poles in its inventory. (I think it's every three or five years, but I don't remember for sure.) I've seen better-looking poles than that snap off (thankfully they weren't being used for power lines).
