10KV高压端计量柜电流互感器型号是LZZBJ9-12 2*750/5,供电局告诉我们倍率是12000倍,不知道他是怎么算的! 高压倍率 :高压10千伏计量 电表是3*220/380 给出...

应该倍率是15000倍。电流互感器倍率是750/5=150,电压互感器是10kv/100v=100(计量电压是100v),所以总的倍率是150*100=15000。跟型号没关系,只看变比数值。12000倍是错误的!电流互感器变比是750/5=150,电压互感器变比是10kv/0.1Kv=100,所以总的倍率是150*100=15000
你用的三相表的型号是什么?如果是3*100的(1.5-6)A三相三线表,倍率应该为15000倍!
应该还有两只10/0.1kv的电压互感器。
