基于主动击穿的绝缘油介电强度测试仪校验系统

Calibration System of Insulating Oil Dielectric Strength Testing Instruments Based on Active Breakdown

针对在稳定校验模式下对绝缘油介电强度测试仪进行校验和检查存在不准确的问题,设计了一种基于主动击穿的绝缘油介电强度测试仪校验系统,该校验系统可为被检测的绝缘油介电强度测试仪在指定的高电压点构造真实的击穿环境。实际应用结果表明,该系统更能准确、客观地反映绝缘油介电强度测试仪的误差和性能。

Considering the uncertainty of calibration and checking the insulating oil dielectric strength testers（IODST） under stability verification mode,a new insulating oil dielectric strength testing system based on active breakdown has been designed.This system provides a real breakdown environment at designated high voltage points for the testing of IODST.The application results show that the new system can evaluate the performance of IODST more accurately and objectively.
