Investigation of the gas bubble dynamics induced by an electric arc in insulation oil

  • In this work, experimental and theoretical studies were carried out on arc-induced bubble dynamic behaviors in insulation oil. Direct experimental evidence indicated that the arc-induced bubble experiences pulsating growth rather than a continuous expansion. Furthermore, a theoretical model and numerical calculation method were proposed, which revealed the dynamic mechanism of bubble growth. Good agreement between the theoretical results and experimental observations verified the general correctness and feasibility of the proposed method.
