The LAZBJ3-10G current transformer is an improved fully enclosed current transformer based on the LAZBJ3-10 model. The secondary is composed of independent measuring windings (1S1, 1S2, 1S3) and monitoring windings (2S1, 2S2, 2S3) protection groups (3S1, 3S2, 3S3), and is equipped with a middle tap to change the current ratio. It is very suitable for places with large seasonal load peaks and valleys, inaccurate measurement and billing, and achieves the purpose of low current ratio measurement and high current ratio protection. Due to the ratio ratio, the primary winding section shared with it is selected according to its high current ratio. For low current ratios, the current density has a large margin. As a result, the overall overload capacity and dynamic thermal stability performance have been improved.
