i bought a phillips noreleco x-ray transformer on e-bay several months ago and can obtain little information with the search engines. no info on transformer case. visual inspection reveals center tapped secondary,2 diodes marked 150 , kv,i guess. seperate capacitor in its own oil filled tank,plus a large resistor which bleads the capacitor to ground when an exposure is initiated. i feel it is a full wave constant potential generator. i would like to know the probable voltage capability. ihave mated the transformer to an antique g.e. control. there is a single hi voltage lead from the transformer,the anode is at ground potential. i am using x-ray tube housing and insert capable of 150 kv but have concerns about the anode being at ground potential.fear tube could be damaged if about 75 kv is exceeded.i get tube current,xras are being produced,but know little else.please address above concerns,explain about constant potential x-ray transformers and how the might be safely used with medical x-ray tubes.
