Main features of electromagnetic current transformer

Electromagnetic current transformer. A current transformer that realizes current conversion based on the principle of electromagnetic induction. 1. Adopt front-end digital technology, optical fiber transmission, good electromagnetic compatibility. 2. Good amplitude-frequency characteristics and phase-frequency characteristics, and high measurement accuracy can be obtained in a wide range of amplitude, frequency and phase. 3. It is a digital sensor, the secondary instrument will not introduce errors, and the sensor error is the system error. Due to the problems of easy saturation, nonlinearity, and narrow frequency bands of electromagnetic current transformers, electronic current transformers have gradually emerged. Electronic current transformers generally have the advantages of anti-magnetic saturation, low power consumption, and broadband.
