对电容型电流互感器两种特殊测量结果的分析

Analysis of Two Special Measurement Results of Capacitive Current Transformer

针对测量电容型电流互感器（型号：LB6—110W）时常遇到的介质损耗测量值偏大或为负值两种情况，探讨了仪器高压引线或测量线与设备接触不良导致测量值偏大及设备接地不良导致测量值为负的原因，并提出了消除方法，从而得到正确的测量结果。

Reasons are analyzed on the extreme large measurement result and the negative value of dielectric loss in capaci rive current transformer （LB6-110W）. The poor contact between high-voltage outgoing lines or measuring lines and equip ments causes the extreme large measurement result, and the bad grounding of equipments causes the negative value. The solu tion is proposed in this paper and the right measurement is acquired.
