Hello all,
I have a 3 phase transformer that a ham told me it could be used to power my
amp.. Here is what the tests revealed, under test, only voltage available was
120 volt, so it was tested with that, now this transformer has 3 seperate coil
windings, and several input voltage ranges from 208 to 245 volt primary, he
took one wire from the 2 of the windings and applied 120 volt, one the
secondary side, the 2 wires yeilded about 3300 volt AC, this transformer is
rated @ 7000 AC volts so on 120 volt thats about right, he used the 240 volt
tap on the primary, but only applied 120 volts, follow me so far, he also said
that I would have to use a bridge design since there is no center tap, the 2
wires from the 2 coils would be the HV to the rectifiers. Can this be used to
power a pair of 4-1000's without any problems from the transformer under load.
I know this is out of the normal for a transformer, but I was looking for about
8 to 9 KV on the plates of the amp. BTW, he said the 3rd
winding and its wire are not used and can be taped up.
thanks, Richard
