| 摘 要： | We design a third Hilbert fractal antenna for partial discharge (PD) monitoring in gas insulated substations (GIS) based on fractal principles, and analyze the Hilbert antenna impedance characteristics using an equivalent inductance method of parallel transmission lines. The PD experiment of metal protrusion defect is conducted employing fractal and microstrip antennae. The test results show that the characteristic of the Hilbert fractal antenna has good performance and can detect the PD signal for online monitoring in GIS. A portable online monitoring and locating system for GIS is established using the Hilbert fractal antenna and LabVIEW. The locating accuracy of the PD source in the laboratory meets the requirements of the PD site location.
