Application:

    Many dielectric and mechanical failures in large power transformers are preceded by mechanical changes in the winding structure. These changes, or displacements in the winding, may be the result of:

    Transportation damage occurring between the manufacturer and the final location.

    Short circuit forces imposed on the windings resulting from a low impedance fault occurring close to the transformer.

    Natural effects of aging on the insulating structures used to support the windings.

    Detection of these displacements ahead of a dielectric failure can reduce unplanned maintenance costs, and provide the possibility to improve system reliability by preventing outages. Additionally, when damage is discovered, repairs may be targeted to a specific phase winding.
