Was wondering if there's some formula to roughly determine the
voltage/current parameters of a super heavy duty filament transformer.
The unit I have has multitap 220VAC primaries with solid buss bar output
terminals (no CT) about the diameter of my pinky. The no load voltage is
about 18.2 to 19.5 depending of the primary tap used. I'm certain the
rating is better than 75amps. It might even be a low voltage weld
transformer. Is there a method to load the transformer and determine
the operating filament voltage under load? Any suggestions would be
appreciated. Unfortunately, the plate clearly lists only the primary
voltage. Thanks, ron W2CQM/3
Plate has the following information:
