Quick Question

[Dairyspark]

Using my test lamps today and I checked it on the wee tester thing and it lit up etc to 690v and I had a thought.........where would I find 690v?

Cheers

[SIZE=12pt]Some 3 phase induction [/SIZE][SIZE=12pt]motors can be connected delta 400v .... the same motor connected in star can be used at 690V.  [/SIZE]

Railways also use different voltages to us mere mortals I believe.

Regularly see 650 or 690V on panels alongside lines, I just can't recall which one it is now though.
