Acoustic Emissions

We place numerous sensors around the exterior walls of a transformer and listen for incipient failure indications within the transformer tank. This test can assess the health of the transformer and direct transformer maintenance personnel as to where repairs may be needed. This testing can also be accomplished on any device that is housed in a tank such as regulator, breaker, etc.
