Features:
High permeability - greatly improved transformer accuracy and reduce difference and angular than the difference
Light weight, low cost - the price was significantly lower than permalloy, cost-effective
Excellent temperature stability - can be -55 - 130 oC to work long hours
Saturation magnetic flux density between silicon steel and Permalloy between - is conducive to reducing the instrument security factor
Application areas:
Measuring Current Transformer Substation Core (accuracy 0.5-0.01 grade, rated voltage 0.5-500kv)
Power transformer is specifically measure current and power transmission lines of special transformers.
According to measurement accuracy class requirements, can choose a different soft magnetic materials as
core. The higher permeability core, the higher the measurement accuracy . At present the greatest amount of
core material is cold-rolled silicon steel, glass and nano-crystalline alloy Mo alloy. In recent years,
high-precision level (such as the 0.2, 0.2S class, 0.5S level) of the transformer demand is increasing rapidly.
When asked to become more than a small, low-security turns, or the core size due to volume requirements
restricted circumstances, the cold-rolled silicon steel sheets often do not meet the required precision.
Although the high permeability glassy Mo alloys meet the required precision, but the price higher.
The use of nano-crystalline core can not only meet the required accuracy and the price lower than the
glassy Mo alloys.
