Abstract

The characteristics of Electrical breakdown liquid nitrogen($LN_2$) were studied under simulated Quenching conditions for application of HTS apparatus. The experimental results for various quench condition revealed that the breakdown voltage of $LN_2$ with bubble flow velocity and gap spacing, Also, it did a electric field and potential distribution interpreting at the liquid nitrogen when the bubble existed, The plots of equipotential lines for three cases are also shown.
