Acoustic Partial Discharge location in transformer
Acoustic Partial Discharge location in transformer
(OP)
Is any one out there dealing with acoustic PD loaction especially inside the transformer winding? Due to different velocities inside the winding it is difficult to use the triangulation procedure. Any suggestions?

(Sorry that it's a slimy-assed grocities link.)
Others here have significant PD experience and will likely post. A search here may point to the exact need.

Cutler Hammer and Triple 5 make ultrasonic devices geared toward monitoring transformers, but they do not perform any triangulation. (you can only get a rough idea of location by finding the spot on the tank where the signal is strongest).

Anyone else have any info?
