在气泡理论的基础上解释了击穿的初始状态发展。对浸在油中的电极施加直流电压会产生小通道。在下一阶段，在电极之间形成电弧通道。等离子体通道的电阻变化从几欧姆到几百mΩ由于焦耳加热引起的高电弧电流流过该通道。电弧电流的动态取决于外围电路的参数，并由RLC电路表示。
The initial state development of breakdown is explained on the basis of bubble theory. Application of dc voltage to electrodes immersed in oil results in the creation of small channels. In the next phase an arc channel between the electrodes is formed. Resistance of the plasma channel changes from a few ohms to a few hundreds mΩ due to Joule heating caused by high arc currents which flows through this channel. The dynamics of the arc current depends on the parameters of the outer circuit and is represented by the RLC circuit.
