摘要：

Nowadays, smart grid online monitoring systems are widely used in high-voltage (HV) power transmission networks, leading to the requirement of reliable power supply units for the monitoring equipment. In this article, we present a novel solution to harvest energy from the magnetic field around a 110-kV transmission line and transmit the energy to the online monitoring equipment on the transmission tower over 1.1 m insulation distance. Printed circuit board resonators are covered by the composite insulation material forming the first HV insulator with wireless power transfer (WPT) capability. The prototype of the HV insulator has passed the rigorous HV tests at 550 kV. The WPT characteristic of the HV insulator including the effects of corona rings is analyzed and verified by practical measurement.
