Abstract

A new, bio-inspired printed monopole antenna (PMA) model is applied to monitor partial discharge (PD) activity in high voltage insulating systems. An optimized sensor was obtained by designing a PMA in accordance with the characteristics of the electromagnetic signal produced by PD. An ultra-wideband (UWB) antenna was obtained by applying the truncated ground plane technique. The patch geometry was bio-inspired by that of the leaf, resulting in a significant reduction in size. To verify the operating frequency and gain of the PMA, measurements were carried out in an anechoic chamber. The results show that the antenna operating bandwidth covers most of the frequency range of PD occurrence. Moreover, the antenna presented a good sensitivity (mean gain of 3.63 dBi). The antenna performance was evaluated through comparative results with the standard IEC 60270 method. For this purpose, simultaneous tests were carried out in a PD generator arrangement, composed by an oil cell with point-to-plane electrode configurations. The developed PMA can be classified as an optimized sensor for PD detection and suitable for substation application, since it is able to measure PD radiated signals with half the voltage levels obtained from the IEC method and is immune to corona discharges.

摘要

一种新的、受生物启发的印刷单极天线（PMA）模型被应用于监测高压绝缘系统中的局部放电（PD）活动。通过根据 PD 产生的电磁信号的特性设计 PMA，获得了优化的传感器。通过应用截断接地平面技术，获得了超宽带（UWB）天线。贴片几何形状受叶子的启发，尺寸显著减小。为了验证 PMA 的工作频率和增益，在消声室中进行了测量。结果表明，天线的工作带宽覆盖了 PD 发生的大部分频率范围。此外，该天线具有良好的灵敏度（平均增益为 3.63 dBi）。通过与标准 IEC 60270 方法的比较结果评估了天线的性能。为此，在由具有点-面电极配置的油室组成的 PD 发生器装置中同时进行了测试。所开发的 PMA 可归类为 PD 检测的优化传感器，适用于变电站应用，因为它能够以比 IEC 方法获得的电压水平低一半的电压水平测量 PD 辐射信号，并且不受电晕放电的影响。
