| 摘 要： | 为了降低传感头的相位差,从传感元件Rogowski线圈及后续处理电路的特点出发,对线圈和后续电路所产生的相位差进行分析计算,在此基础上设计合理的相位补偿电路,并给出试验结果。结果表明,相位调理电路完全能够补偿传感头所产生的相位差,从而使电流互感器的精度达到国标0.2级标准。

| Abstract: | Solving sensor's phase difference is essential for improving the precision of electronic current transformer.In order to reduce the sensor's phase difference,according to the characteristic of Rogowski coil and subsequent disposal circuit,this paper analyzed and calculated the phase difference of sensor.Then,reasonable circuit compensating the phase difference was designed.At last the test result was presented.The result indicates that the phase compensation circuit could compensate entirely the phase difference induced by sensor.So as to,the precision of current transformer could be improved to 0.2 level. |
