Application

● High-voltage current transformer cores (our MLGH series) is mainly used in high-voltage transformers and high-voltage, high-current power plants and substations.

● Precision current transformer core (our MLJH series) 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.

● Zero-sequence current transformer core (our MLLH series) is mainly used in the leakage protection switch

Features

Compared to conventional soft magnetic alloys (e.g. silicon steel and Permalloy), our cores have 4 features.

● High magnetic permeability – reduces measurement errors in current transformers.

● High saturation magnetic induction – smaller size and lighter weight than permalloy current transformers.

● Low loss – the ideal material to replace Permalloy.

● Excellent temperature stability – long operating time from -55 to 130 °C
