化工变电站改造后母线电压互感器计量误差问题的分析及对策

Analysis on Problems During Error Test of Chemical Industry Substation Retrofit Pressure Transformer and Countermeasures

文章由化工某变电所改造后母线出现超大计量误差展开分析与研究,指出电压互感器过负荷导致计量误差超过允许范围,从而针对由电压互感器容量偏小导致计量出现大误差的现象提出解决的方案和建议。

The paper presented concluds the problems occurred during test of chemical industry substation retrofit pressure transformer, analyzed the causes was overload error of pressure transformer, overload which was too small for the capacity caused by the voltage transformer error of measurement of the phenomenon of big and propose solutions and recommendations.
