Abstract: The growth of microbubbles under the action of a negative pressure wave in transformer oil (TO) has been studied. It is established that microbubbles in TO grow to a detectable size of 100–200 $\mu$m. According to the results of calculations, these bubbles can develop from the nuclei of micron and submicron dimensions.
