In order to improve test efficiency of launch vehicle and optimize the process of prelaunch testing, and to alter the traditional method of disconnecting electric cables manually for leakage monitoring, based on maintaining the original power supply circuit, a leakage monitoring technology research for the medium frequency alternating current supply circuit is proposed and developed. At the same time, the precision of leakage monitoring circuit is analyzed and the self-detection method is used to advance the reliability and safety of the system. The test results show that the system realized online leakage monitoring lasting no less than 24hours, and the range of leakage monitoring is 500 kΩ~50 kΩ with the precision better than ±10%, satisfying the monitoring requirements. Finally, the system experiment is carried out in the prelaunch testing of large cryogenic launch vehicle with high-reliability, high-precision and high-efficiency, and has significance of improving the level of automated testing and realizing unattended fore-end of launch vehicle.
