The role of nanodielectrics in the electrical power system is becoming crucial owing to its superior properties and potential applications in the field. Yet, the materials face limited breakdown strength and thermal properties. Further, the nanodielectrics have not found a comprehensive commercial platform because of the costly manufacturing process, and characterization and testing facilities. Therefore, to reduce the involved cost, in this work, an FE (finite element) based computational technique has been implemented to visualize the effect of shape, size, and filler concentration under the application of high voltage (HV). The epoxy-based nanodielectrics have been modeled incorporating a range of different shapes and size nanofillers—Al₂O₃, BN, BeO, SiO₂, and TiO₂. The paper discusses the 2D-analysis of the modeled nanodielectric in the steady-state electrostatic fields and thermal domains. It shows the insights of the nanofillers’ choice to ensure a perfect blend of electrical and thermal properties. The epoxy with square-shaped BeO fillers showed a rise in the electric field of nearly 1.5 times than unfilled neat epoxy, which indicates a significant surge in thermal conductivity at specific filler loading.

由于其优异的性能和在该领域的潜在应用，纳米电介质在电力系统中的作用变得至关重要。然而，这些材料面临着有限的击穿强度和热性能。此外，由于昂贵的制造过程、表征和测试设施，纳米电介质还没有找到一个综合的商业平台。因此，为了降低所涉及的成本，在这项工作中，已经实施了基于 FE（有限元）的计算技术来可视化在高压 (HV) 应用下的形状、尺寸和填料浓度的影响。已对环氧基纳米电介质进行建模，其中包含一系列不同形状和尺寸的纳米填料——Al ₂ O ₃、BN、BeO、SiO ₂和TiO ₂。本文讨论了稳态静电场和热域中模拟纳米电介质的二维分析。它显示了纳米填料选择的洞察力，以确保电学和热学性能的完美融合。与未填充的纯环氧树脂相比，带有方形 BeO 填料的环氧树脂的电场增加近 1.5 倍，这表明在特定填料负载下热导率显着增加。
