930y480 / 896y460

I've read this is a common voltage in the oilfields. I cant seem to find what is used for fusing. Everything seems to jump from 600vac to medium voltage.

I was thinking it would be a decent solution doing a step up step down for some of the well pumps runs I've had to to at 3000+ ft. It's a decent bump over 600v, but able to use off the shelf 480-240 transformers in a wye bank.

Most all xhhw-2 is now 1kv rated, just unsure of what's available for cost effective ocpds. As far as I can tell a 600v fuse would only be ok for a line to neutral load.

Interesting question. I'll let an engineer take this one. One thing to note the voltages for a Wye system in your thread title are incorrect. 480*1.73=830

Interesting topic. We did a few variable speed drives for the oil industry and cement works. There were Static Kramers. They were all custom systems 900V.
