Three Phase Transformer

A three-phase combined transformer is a transformer used for measuring, measuring or protecting three-phase electrical energy in a power system, which is composed of a three-phase voltage transformer and three single-phase (or two single-phase) current transformers. All instrument transformer meet IEC60044-1,2, IEC61869-1,2,3, ANSI/IEEE C57.13, GB1208-2006, GB/T 20840.1-2010, GB/T 20840.2-2014, GB/T 22071.1-2018, IEC/EN61010-2-032, IEC/EN61010-2-031, IEC60185, JJG1021.
