Transformer Acoustic Emissions
INEL did experimental research on this for the US Naval Civilian Engineering Lab several years ago, and was able to detect acoustic emission correlated with partial discharge in a cast coil transformer. They are seeking funding internally to continue with this work.
While the original work was done on cast coil units, the sensors that were developed could be used just as well to monitor other systems. They would be cheap to make and could be made part of an integrated comprehensive substation monitoring system (i.e., IDMS).
