Belt magnetic cores made of high-permeability amorphous alloys and high-permeability compound (nanocrystal) material for measuring current transformer
High initial permeability（高初始导率）
Relative permeability of magnetic core with core size <600 mm at 50 Hz must be:（相对磁导率）
|
Range of magnetic field intensity Hm, А/m 磁场强度范围 |
In the case with ring or oval core 在有环或椭圆形芯的情况下 |
In the case, with rectangular core and without case, with ring/oval core 在这种情况下，有矩形的核心和没有的情况下，环/椭圆形的核心 |
Without case, with rectangular core 没有表壳，有矩形芯 |
|
