相位分辨的局部放电（PD）数据已被记录从电气树生长在一个灵活的环氧树脂，硅凝胶和硅橡胶与纳米填料和没有。环氧树脂样品和有机硅凝胶样品不含任何填料颗粒。在硅橡胶的情况下，使用有机蒙脱土（oMMT）纳米填料。在20-60°C范围内的不同温度下进行电树枝化实验。在电树生长过程中的PD动力学的细节已被发现显着改变与温度在一些聚合物系统的调查。尝试识别的功能，这是目前在PD模式，无论主机聚合物矩阵使用PSA图和独特的局部放电过程中的电气树。这些功能可用于对实际电气绝缘系统进行可靠的诊断和状态监测。
Phase resolved partial discharge (PD) data have been recorded from electrical trees grown in a flexible epoxy resin, a silicone gel and a silicone rubber with and without a nanofiller. The epoxy resin samples and silicone gel samples did not contain any filler particles. In the case of silicone rubber, organo-Montmorillonite (oMMT) nanofiller, was used. The electrical treeing experiments were carried out at different temperatures in the range 20-60°C. The details of PD dynamics during the electrical tree growth have been found to change significantly with temperature in some of the polymer systems investigated. An attempt is made to identify features which are present in the PD patterns irrespective of the host polymer matrix using PSA plots and unique to the partial discharge process in electrical trees. Such features can be used for reliable diagnostics and condition monitoring of real-life electrical insulation systems.
