Current transformer on-line detection auxiliary measurement adjusting system and method

The invention belongs to the technical field of current transformers, and particularly relates to a current transformer on-line detection auxiliary measurement adjusting system and method, and the system comprises an access module which is used for connecting the secondary side of a current transformer, and leading out the secondary side current of the current transformer through the secondary side access end of the current transformer; the switch module adopts a multi-control switch and is used for controlling the flow direction of the secondary side current of the current transformer; and the control module is used for converting the received secondary side current of the current transformer into a voltage signal through a signal converter, and performing data comparison on the obtained voltage signal and the input current signal to realize auxiliary measurement adjustment of the current transformer. According to the invention, required voltage is output to the primary side of the current transformer accord
