Energy Meter Soft Magnetic Core
Soft magnetic cores play an important role in the current measuring applications. In many circumstances, DC immune cores are required in the current transformers of energy meters. Our amorphous & nanocrystalline dual cores can work properly in the circuit when there’s direct current, as well as normal sine wave current. After devoting to the area of CT cores for more than 15 years, we can design customized DC immune composite cores for smart meters of different accuracy class, and provide quick prototype developed samples in a couple of days.
