The use of nanocrystalline and amorphous materials for electric energy metering improvement and reducing the effects of external magnetic fields
Віталій Васильович Волохін, Illia Mykolaiovych Diahovchenko · 2016
Current transformer sensors, loaded by a precision resistor, are widely spread in electric energy metering devices. The core of such appliance is made from iron-based materials. So it comes in the magnetic saturation when a constant component of current is present or when current overloads occur, which affects the accuracy of energy accounting. Additionally, there is a possibility of electric energy meter' readings distortion due to the impact of external magnetic field on transformer sensors. In this article it is shown how the use of nanocrystalline and amorphous alloys helps to neutralize these negative influences.
