    Tips: What is the rated current of Split core current transformer?

    Primary rated current: the load current allowed through the primary winding of the current transformer. The primary rated current of current transformer used in power system is 5~25000A, and the precision current transformer used in test equipment is 0.1~50000A. Current transformer can run under primary rated current for a long time, when the load current exceeds the rated current value, it is called overload, and the long-term overload operation of current transformer will burn out the winding or reduce the service life.
