Suspended movable bubble defect is often ignored during power transformer partial discharge (PD) detections. The key problem is the lack of PD simulation test platform for this kind of insulation defect. The current study designed a test platform to generate PD from suspended movable bubble defect. PD signals were detected using ultra high frequency (UHF) methods. The experimental data indicated that the device can simulate suspended movable bubble defect in oil that causes PD, and the PD signals show different characters with still bubble defect .
