Hi, here is what i know from little experience, if the high voltage
connections are angled out chances are they are potential transformers, if
the high voltage connectors are strait up out the top probably is a current
transformer and ng for coil work. potential transformers are apt to have
higher ratios, like 60:1, or 90:1 or 100:1 where current transformers tend
to have ratios like
40:15 etc.  first thing i look for is angled high voltage connectors, then
for the ratio, some are marked potential transformer but not all marked are
the ones we can use for coiling. cul brian f.
