超导磁悬浮系统需要大量的接地线圈：推进线圈和悬浮制导线圈，因此如何监测接地线圈的状态是实际运行中的一个大问题。在我们以前的论文中，我们已经证明了机载无线电干涉仪系统对于探测和定位在异常推进线圈中发生的局部放电（PD）源是有效的。我们将两个无线电干涉仪系统安装在由转向架和小车组成的试验车上，用于检测和定位宫崎磁悬浮试验轨道u型导轨上异常推进线圈中的PD源。结果表明，在试验车辆以50km/h的速度行驶时，利用车载无线电干涉仪系统可以发现异常推进线圈。
Superconducting magnetic levitation (Maglev) systems require a large number of ground coils: propulsion coils and levitation-guidance coils, therefore how to monitor the condition of ground coils is a big issue for the real operation. In our previous papers, it is shown that an on-board radio interferometer system is effective for detecting and locating a partial discharge (PD) source occurring in an abnormal propulsion coil. We mounted the two radio interferometer systems on a test vehicle consisting of a bogie and a car for moving-detection and location of a PD source occurring in an abnormal propulsion coil arranged on the U-shaped guideway of Miyazaki Maglev test track. It is shown that the abnormal propulsion coil could be found by using the on-board radio interferometer system while the test vehicle was driven at the speed of 50km/h.
