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 about the nonlinear conductivity theory of composite materials. In particular, the key issues about nonlinear conductivity studies of composite materials are proposed. The nonlinear conductivity mechanisms of two typical filler particles (SiC and ZnO) are introduced. In addition, two kinds of nonlinear conductivity theory, including the traditional dielectric conduction theory and the polymer conduction theory, are reviewed. Several mechanisms in each of the conduction theories are analyzed, and also, the advantages and disadvantages of these theories are presented in detail. Thus, the purpose of this paper is to let the researchers know the nonlinear conductivity research status fully. We believe this paper is of great significance for the nonlinear dielectric conductivity researchers.

“…Duzkaya and Beroual [14] showed that natural ester-based nanofluids with ZnO nanoparticles as semiconductive can make the AC breakdown performance better. Recently, Xie et al [15] reveal that the SiR/ZnO composites have a significant smoothing effect on nonuniform AC electrical field at the tip and suppress corona discharge. In [16], by using ZnO varistor as a material with nonlinear conductivity, the electric field in the cable terminal accessory was diminished.…”

The electric field distribution of insulator surface is nonuniform, and the maximum electric field is visible around two terminals of the insulator. Using a microvaristor layer is one of the methods of field control that can reduce the electric field stresses to prevent an extension of discharges on the insulator surface and a complete flashover caused by the subsequent development of arcing. This study targets the effect of zinc oxide (ZnO) microvaristors on the electric field distribution along the contaminated and clean composite insulators that have been investigated. In addition, the impact of the insertion of microvaristor layers on the critical flashover voltage (CFO) of the insulators through a mathematical formula has been presented for the first time. The estimation of electric field distribution is conducted through finite element method (FEM) on a 400 kV insulator using COMSOL Multiphysics, in which the optimal dimensions of the microvaristor layer were obtained using the accelerated particle swarm optimization (APSO) algorithm. Then, for the first time, the analysis of the influence of the ZnO insertion on the transient performance of the insulator, i.e., the outage rate of the network, is performed in EMTP software for the insulator with the optimized insertion of the microvaristor layer. Modelling techniques were used to simulate the components of a transmission network according to the valid models. Finally, by setting different values for CFO, Monte Carlo simulation, and linking EMTP and MATLAB software, the lightning flashover rate (LFOR) and the failure risk (F.R.) of the different insulator models are calculated. It is shown that the proposed method reduces the maximum electric field of the inside and outside of the insulator, which in turn leads to a reduction in the outage rate of the power network and the insulation risk of the insulator, and an increase in CFO of the insulator.

“…It was found that the composites showed obvious non-linear conductivity behaviors when the volume fraction of ZnO fillers reached 14%. He et al [ 12 ] found that the SiR/ZnO composites can make the electric field uniformly distributed at the tip and suppress corona discharge. Nelson et al [ 13 ] introduced the SiC particles into silicone rubber polymer to improve the electric field distribution.…”

In this paper, SiC/epoxy resin composites containing different amounts of micro-sized SiC with different crystal morphologies were fabricated to study the effects of crystal morphology and temperature on non-linear conductivity characteristics. The research results illustrate that the β-SiC particles can provide a higher non-linear conductivity, compared with the α-SiC particles. The presence of temperature also affected the non-linear conductivity behaviors of the epoxy/SiC composites. When the α-SiC content was low, the non-linear conductivity coefficient of the composites increased rapidly as the temperature increased, but the non-linear conductivity decreased slightly as the temperature increased when the filler concentration was large enough. To reduce the influence of the electric field concentration effect by the increase in power density on the power module packaging, the voltage sharing application of the SiC/epoxy composites was simulated by COMSOL Multiphysics (v5.2a, COMSOL Inc., Stockholm, Sweden). The results show that the composites with non-linear conductivity can reduce the electric field stress. The emerging insulation material obtained by the SiC-modified epoxy resin can effectively promote electric field distribution uniformity, and ensure the safe operation of the power module.
