Rich is right - it's a very useful tool. I was lucky enough to find a DC-powered inverter that goes up to 9kV, and powered it from a variable DC source. It works FB and can show a lot of new informat

I had a transformer here, but I sold it to a fellow who needed a high-pot tester.. However, a friend who has one measured the secondary v at c. 600v with 12v on the 120v primary. Are you sure you ar

Due to the current requirement difference, the two windings probably have unequal resistances. There are three color coded pri. wires. What are the resistances? Rich... R. L. Measures, 805-386-3734,

Although a dual primary has the same number of turns on each winding, you can expect slightly different resistances (maybe up to about 10%) because the winding on the outside needs a longer length of

It *not* true to say that a centre-tap will be half the resistance of the full windings. I hit this once when making resistnace mesurements on a 1800-0-1800V tranny. Once half had about 30% (from me

This is not your average dual voltage transformer, Ian. The primary has 3 wires instead of of the typical 4 wires. Rich... R. L. Measures, 805-386-3734, AG6K -- FAQ on WWW: http://www.contesting.com
