Vo-Tech transformer lab station

[joerm]

I've recently acquired







a FlexLab teaching transformer station and am trying to find out more information about it.
It is wired for 3 phase with 3 single phase NWL 3 kva transformer below the desk surface. What looks like a telephone switch operators box on top has female jacks use to dial in various primary and secondary voltages. Would this unit have value as a testing station for when working on various motors with various voltage requirements? Has anyone seen a similar transformer teaching unit? Any info would be greatly appreciated. I don't have any of the cables that would push in to the dash board.

WOW, don't see one of those every day. I think it would be great for testing and evaluating things.

I remember the cables from school days, but have no idea where you could get some. My guess is that they were custom made for the tester.

Pretty much useless imho - despite its retro/steampunk appearance.

You'd get more use from 3 variacs (one per phase and infinitely adjustable) without having to 'select' the required tapping points - if you actually wanted to have a 'useful piece of test equipment'.

Might be worth re-working into a test bench with a selection of different pieces of test equipment in that large back panel unit though.
