Application

High-voltage current transformer cores (SWHGNO) are mainly used in high-voltage transformers and high-voltage, high-current power plants and substations.
The precision current transformer core (SWHJNO) is mainly used in electronic watt-hour meters, precision power meters, current overload protection in mechanical control, current control in industrial automation, and smart meters.
The zero-sequence current transformer core (SWHLNO) is mainly used in the leakage protection switch.

Compared with traditional soft magnetic alloys (such as silicon steel and permalloy), SWH series cores have four features:

High magnetic permeability - with the current transformer measurement error reduced;

? High saturation magnetic induction intensity – small size and light weight compared with the permalloy current transformer
? Low loss – as the ideal material instead of permalloy;

Excellent temperature stability - working at -55~130 °C for a long time.
