Experiment Results on AC Tracking Resistance of ZnO/Epoxy Microcomposites

In order to meet the increased demand for electrical energy, the application of advanced technologies to the power transmission network has increased. Representative examples include HVDC, UHVAC and FACTS. In order to apply such technologies, development and operation of novel power equipment that support fully functionality of such technologies are required. In addition, research on electrical insulation performance is also required to realize safe and stable operation of power equipment. With such background, this paper reports test results of the tracking resistance of epoxy composites filled with micro sized ATH and ZnO particles. Results of the inclined plane test (IPT) showed that micro-composites could show improved tracking resistance performance compared to pure epoxy specimen.
