摘　　要：电压互感器在电力系统中所发挥的作用非常重要,互感器在电力系统正常工作运行下的一次绕组与线路是并联的关系,二次绕组则与继电器或是仪表并联,如果在对高压线路的电压进行测量时电压互感器二次回路的降压不稳定,就会导致用电安全系数降低,所以采取相应的措施对变电站公用柜电压互感器二次回路进行改进非常有必要。The voltage transformer in electric power system plays an important role in the power system, transformer running down a winding and line is a parallel relationship,the two winding and relay or instrument in parallel,ifmeasured at the voltage on the high-voltage line two loop of voltage transformer blood pressure is not stable,will lead to reduced electrical safetycoefficient,so take the corresponding measures to the two loop of voltage transformer substation utility cabinet is very necessary to improve.
