介质损耗测量仪是进行电力设备和绝缘油介质损耗因数测量的专用仪器。为保证量值准确可靠，需定期对其进行校准。由于测量仪输出电源频率和对电介质假想模型的不同，校准数据之间会呈现较大的差异，极易造成结果的误判。本文结合介质损耗因数测量原理，对高压介质损耗测量仪和绝缘油介质损耗测量仪校准工作中出现的数据展开了详细的分析，为科学客观地评判此类装置的计量性能提供良好的指导。

Dielectric loss tester is a special instrument for proceeding dielectric loss factor test of power equipment and insulating oil. It should be calibrated periodically to guarantee the accuracy and reliability of it’s quantity value. Due to the differences of the tester’s output power frequency and dielectric’s imaginary model, there will be great differences between calibration data, which will lead to misjudgment of results. This paper, combined with testing principle of dielectric loss factor, gives a detail analysis of data which appears in the calibration work of high voltage dielectric loss testers and insulating oil dielectric loss measuring instruments. The paper can give a good guidance to evaluate the metrological performance of the testers more scientifically and objectively.
