Current transformer core_CORE SERIES_ANHUI WENERGY ELECTRONIC TECHNOLOGY CO.,LTD

► Features ( Current transformer core ) :

The better the magnetic properties of the transformer core, the measurement error is smaller, the higher the accuracy. Require low ampere turns ratio small, cold rolled silicon steel reach the measurement accuracy, the permalloy core due to low saturation magnetic flux density and high cost because of the use of very constrained.

Nano-crystalline cores are getting wider usage for the 0.2，0.2s, 0.1 accuracy grade precious current transformers because of its high permeability, high magnetization and lower cosl in Ihc field of power supply systems, power energy measurement and controlling systems, dynamical system, relay protection, etc.

► Advantages ( Current transformer core ) :

● High permeability -- Increase CT’s accuracy level

● High magnetization -- Decrease CT meters security factor

● Excellent cost performance -- Lighter weight , smaller volume

● Good temperature stability -- Keep stable from -55℃ to 130℃ for long time
