 JDG4-0.5系列电压互感器为干式绝缘，双线圈户内安装型单相电压互感器，供50/60Hz、0.5KV交流电压及以下电力线路中作电压电能测量及继电保护使用。出线端标记：一次为A、X，二次为a、x。当一次有电压时二次线圈不得短路，否则互感器将被烧毁。
JDG4-0.5 series voltage transformers are dry type insulation, two coils, in house installation ａnd single phase. Adapted to 50/60Hz, rated voltage 0.5kV low voltage power system, as voltage ａnd power metering ａnd relay protection. Marks on the terminals as A ａnd X for primary, a ａnd x for secondary. When the primary is live, the secondary coli cannot have short circuit, or that the transformer will be burnt.
