| 摘 要： | 电压互感器的误差与其二次负荷是直接关联的,现场测试应在电压互感器的运行电压以及实际二次负荷下进行。文中针对由于电压互感器实际的二次负荷与检验规定值(25%～100%)额定负荷相差较大,以致使运行电压互感器误差超差的原因进行了分析和讨论,提出了解决方法。

| Abstract: | Error of voltage transformer is directly associated with its secondary load, the site test must be conducted under working voltage and actual secondary load. This article analyzes and discusses the cause of error overrun of the 220 kV voltage transformer in operation in view of largish difference between the actual secondary load and specified probative 25%~100% rated load and puts forward a solution. |
