> 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、N,二次为a、n。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 N for primary, a and n for secondary. Whenthe primary is live, the secondary coli cannot have short circuit, or that thetransformer will be burnt.
