Abstract

See full text

The disclosure relates to a method for determining and/or monitoring the breakdown voltage of a transformer oil, comprising the steps of

    a) performing an acoustic impedance measurement of the transformer oil, the impedance of a medium partially or entirely disposed in the transformer oil and capable of naturally vibrating and/or transmitting vibrations to the transformer oil is determined in at least one frequency band of defined frequency width; andb) calculating a resonator quality factor for the frequency band based on the determination performed in step a); andc) calculating an acoustic disbalance of the transformer oil based on the calculation performed in step b); andd) ascertaining the breakdown voltage of the transformer oil based on the calculation performed in step c).
