Application of current transformer to detect single-pole current pulse

- Aug 12, 2019-

According to the different methods of the current transformer core reset method, there are two types of circuit types: self-reset and forced reset. After the self-resetting is lost in the original side of the current transformer, the reversing voltage is generated by the negative voltage generated by the open circuit impedance of the secondary side of the current transformer. The reset voltage is related to the magnetizing current and the open circuit impedance of the current transformer. The forced reset circuit is added with a large reset voltage during the loss of the original direct current pulse to achieve a fast reset of the magnetic core in a short time.https://www.ctsensorducer.com/
