基于市场上对全自动、数字式及有较强抗干扰能力为特征的介质损耗测量仪的迫切需要，在基波相位分离算法基础上，采用45 Hz和55 Hz两种频率的变频电源避开工频干扰，用这两种频率各测量5次，将所有测量值的平均值作为被测试品的介质损耗角正切值，并给出了以dsPIC30 F4013为核心的该测量仪器的实现方案。试验结果表明，这种介质损耗测量仪具有运算速度快、测量精度高、抗干扰能力强等特点，具有广阔的应用前景。

Based on the urgent need for a kind of dielectric loss measuring instrument which is char -acterized by fully automated , digital and strong anti-interference capability on the market , rely on a fun-damental waves phase separation algorithm , use 45 Hz and 55 Hz( two frequency ) power to avoid normal interference , the measurement must be operated 5 times under both frequency and the average of all measured values will be take as the tangent value of dielectric loss angle .Besides , the implementation plan of the measuring instrument with dsPIC 30F4013 at its core is provided in this work .The test results show that this instrument is of fast operation , high accuracy as well as good anti -disturbance ability , and has broad application prospects .
