摘要
通过理论分析和试验数据研究,发现了变电站10kV母线上广泛使用三相五柱式电压互感器,而较少甚至基本不使用结构比其简单的三相三柱式电压互感器的原因。
Through theoretical analysis and the study on experimental data, the reason is discovered that the lOkV busbar of the substation widely used the three-phase five- core limb voltage transformer instead of the three-phase three-core limb voltage trans- former with simpler structure,
