Product Description

Application areas:

Masuring-level cirrent transformer used in power system, transformer used on precision measuring instruments (such as watt-hour meter)

According to the requirements of different measurement accuracy of the transformener, different soft magnetic materials can be chosen as iron core materials. The higher the permeabilty of the iron core is. The smaller the measurement error of the transformer is. Hence the accuracy is higher. At present, the more common iron core material is cold-rolled silicon steel sheet, followed by Permalloy and nano-crystalline glass alloy.

In recent years, demands for trandformers with high-precision level(such as class 0.2, class 0.2S and class 0.5S) increased rapidly. When small ratio, low ampere tums are required or the iron core is restricted because of the small volume, the cold-rolled silicon steel often fails to meet the accuracy requirements. Althous the Permalloy iron cores with high permeability can meet the required precision, its price is very high

However use of nano-crystalline alloy iron cores can both meet the accuracy requirements and be produced at lower cost than the permalloy. Theefore, the demand of measuring level current transformer iron core made of nano-crystalline alloy rapidly increased domestically.
