摘　　要：介绍了绝缘理论中的Garton效应,利用一只发生Garton效应的CVT,低电压介损测量结果比对,掌握了Garton效应影响CVT介损测量的规律,并提出了现场试验中判别CVT发生Garton效应的方法及处理建议。The Garton effect in insulation theory is expounded. Based on the comparison of the low voltage dielectric loss measurement results of a CVT with Garton effect, the law of Garton effect affecting CVT dielectric loss measurement is grasped. The methods and treatment recommendations are put forward to judge if Garton effect occurs in field tests of CVT.
