Amorphous alloy current transformer uses amorphous alloy material as the core material, which better solves the problems existing in the traditional current transformer. Amorphous alloy has the advantages of low hysteresis, low loss and high saturation magnetic induction strength, which can effectively improve the measurement accuracy. In addition, amorphous alloy current transformer has the characteristics of small size, light weight, flexible installation, etc., which is convenient for the installation and use of equipment.
