摘　　要：由于传统的电能表与数字电能表的工作方式不同,所以传统电能表校验台无法对数字电能表进行校验。因此,设计了一种新的数字电能表计量校验装置。介绍了数字电能计量系统和数字电能表校验仪的工作原理。该校验仪的准确度达到了0.05级,抗干扰性能好,能够适应现场复杂的测试环境,并且具有很好的便携性,能够满足常用数字电能表校验的需要。Since the working mode of traditional electric energy meter is different from that of the digital electric power me-ter,the calibration platform for traditional electric energy meter can not calibrate the digital power meter. Therefore,a new me-trology-calibration device for digital electric power meter was designed. The working principles of digital electric power metrologi-cal system and digital electric power meter are introduced. The accuracy rate of the new calibrator reaches the level of 0.05,can fit the complex testing environment in spot and meet the requirements of digital electric power meter calibration,and has strong anti-interference capability and good portability.
