ECN Forum Forums General Topics of the Trade Non-US Electrical Systems & Trades Non standard voltages

It was on 3 news last Monday night. An article on Transit NZ and the controversy surrounding their roading projects. I guess Transit NZ was showcasing their largest project to prove they are doing something to relieve the traffic congestion around Auckland.

Thanks Kiwi,
I will try to get hold of a copy from TV 3, or a digital file.
I saw the machine at work yesterday, in very dusty and arduous conditions.
Cheers Ray

[i]Just a thought, but in round figures 1050V would be the phase-to-phase voltage on a wye system with 600V phase-to-neutral -- 600 x SQRT(3) = 1039V. 600V is a standard voltage in a few places -- Canada for a start, so perhaps there's a link?[/]

600V is a standard voltage in Canada, but it's a phase-to-phase voltage. The phase-to-neutral voltage on these systems in 347V. We also have 480/277V systems, but these tend to be older systems or equipment imported from the U.S.
