Where is 416V used?
(OP)
We are designning a replacement hydralic pump package for a customer and they are asking for a motor that will operate at 416v/60hz and 460v/60hz.
Where is 416 used and is it a standard voltage? Or are they planning for 460v with brown outs?

RE: Where is 416V used?
I did a walk through of the little utility that I consult for. Since my last inspection, A sewage treatment plant and pumping stations had been installed.
The transformer banks were connected wye-delta.We do not allow wye-delta connections on the system.
I presented the following options to the designers.
1> reconnect the 240:480 Volt transformers for 240:416 Volts and give assurances that the pump motors will operate safely on 416 Volts.
2> Supply and install 277 Volt transformers for 277:480 Volts.
3> Supply and install autotransformers or an isolation transformer to boost 416 Volts up to 480 Volts.
In the months that the wye:delta banks were in service before I got there they caused two transformer burnouts, probably a motor burnout and numerous primary fuse failures.

Using Keith's link, I guess your answer might be "Guyana"

I'd challenge the requirement because it sounds like he wants a motor for a 50 Hz, 380-420 volt European system, not a 60 Hz 416 system.
About half of the motors in the turbine building are dual-rated for 380-420 volt 50 Hz, and 440-480 volt 60 Hz, the rest (particularly the very large ones) are 50 Hz.

About 10 years ago I was involved in a project to upgrade some motors from 25 Hz, supplied by a power station at Niagra Falls that Ontario Hydro were trying to phase out.
I wonder if it was the one Tesla designed?

I was a service engineer for a major turbine mfg in the New Orleans area quite a few years (decades) ago and while I never did get dispatched to a 25 Hz station, (Sewage and Water Board Stations) several of my co-workers did, probably since they had the experience at those stations and I didn't.
They had their own 25 Hz power plants to generate the power for the pumping station motors many of which were flooded after the storm, pumping stations and power plants as I remember it.

Broken Hill in Australia has (had?) a very large mining facility running on 40 Hz from Diesel generators and many dollars in fuel. ABB did a solid-state converter to turn our 50 Hz supply into 40 Hz for them, enabling the diesels to be put on standby or whatever.
