1、 聚合物绝缘在直流高压下的电荷输运与积聚机理
提出了基于注入电荷抽出受限的电荷输运理论，系统地解释了高温高场及温度梯度下的空间电荷积聚等一系列问题。相关论文多次被国内外知名学者引用，并作为“注入电荷抽出受限”理论的代表作；其中空间电荷对试样厚度依赖性的研究被目前世界最大的高压直流电缆厂商ABB公司多次重点引用；结合高分子链段在强电场下的松弛运动，成功模拟了快速空间电荷包的形成和输运，为这一难题提供了系统合理的解释。
2、聚合物绝缘在交流高压下的电树枝和局部放电机理
电树枝的起始与发展与局部放电密不可分，局部放电为电树枝的发展提供能量，而电树枝的形态和特征又影响局部放电的特性。以往研究创新性地采用3D XCT表征了电树枝的形貌，验证了微米填料延缓电树生长的作用机理；提出了定量分析局部放电内在机理的新方法；建立起了电树枝与局部放电之间的定量关系。
3、绝缘材料在高压下的老化寿命评估
提出了基于逐步升压法测算老化寿命指数的新方法，系统研究了电压类型、纳米填料、电荷积聚等对绝缘老化的影响。该方法已多次被国内外同行采用，具有较大的工程应用潜力。
