This type of current transformer is mainly used indoors, are applicable for alternating current systems of rated voltage up to and including 0.66kV and rated frequency 50Hz or 60Hz, used for current and electric energy measurement or relay protection. It is of moulded-case current transformer, is widely used in switchgear assemblies, can adopt installation method of busbar fixation or base plate fixation, can be installed in any direction, either busbar or cable can be used as primary conductor.
1. Rated secondary current: 5A or 1A;
2. Power factor: cos中＝0.8 (lag) ;
3. Rated frequency: 50Hz or 60Hz;
4.Rated primary current, rated output and accurate level see table 1.,
5.Insulating property: primary winding to secondary winding and ground, and secondary winding to ground can bear the power frequency withstand voltage 3kV for 1min.
