When the sample thickness increased from 200 μm to 400 μm, the DC conductivity curve shifted to the right, I Leakage dropped from 2.69 ×10−8 A to 1.43 ×10−9 A, and U1 μA rose from 459 V to 962 V. The ...

Nonlinear conductivity dielectric is widely used today to solve high energy discharge problems in many fields (such as spacecraft charging and motor insulation). This paper summarized the research ...
