In actuality, they are pretty serious about things out here... This (along with alot of other leases owned by the company we're working for) have been passed from owner to owner many times, starting life as Unocal Oil. As alot of the Midway Sunset leases were developed between the 40's - 70's, we come across all kinds of strange ideas. This facility is from the 60's, and has likely been operating like this since then. The current lease owner has had possession for about 3 years now and is steadily coming across these things and cleaning them up as they show.... After alerting them to the fused neutrals and the barely up there transformer, I'm told we'll be addressing them this coming week. (Oil is about $90/barrel... it's not like they're broke or something!)
Marc, the 15KVA is also feeding a control building for the water plant (you can see part of it in the 1st pic, the last disco with the 80A fuses is for the control building subpanel! PLC's and computers on a fused neutral
I am very concerned that a 120 or 240 volt light is mounted above the HV conductors. My overhead standards book requires around 3 or more meters vertical separation. Anyone servicing that fixture has to break a lot of rules to work there. Close limits of approach, Hot stick work and line trucks to change light bulbs. The main switch should be rated or equiped with a neutral block and should be marked for use as a service entry.

I initially thought the same thing, but looking at the first picture more closely it looks like those overheads are actually the 480 feeds to the transformer primary. I've never seen cutouts in low-voltage distribution but, then again, what I know about O/H I could write on a matchbook.
