Hello Techies,

This may be a little off topic but here goes:

I'm looking for a standard (IEEE preferred, but anything would be fine)
for high voltage, high current testing or more properly, characterizing,
of a transformer like coil. A high voltage pulse would be applied to an
inductive device under test. The inductor would have a test capacitance
across it and after the pulse was applied, the ring down current and
voltage would be monitored as a signature profile is looked for. The
purpose is to look for turn to turn shorts which appear only under high
voltage operating conditions. Standard HiPot tests don't apply since we
are looking for turn to turn faults which. Simple resistance tests don't
apply either since the fault only appears under high current conditions.
We are trying to develop a test whithout requireing our vendor to
purchase high current continuos wave amplifiers.



Thanks in advance,

Paul Orlando
