1.       Brief introduction

Current transformer of power system plays the important role in providing a current in its secondary winding proportional to the alternating current flowing in its primary. They are commonly used in metering and protective relaying in the power plants and substations where they facilitate the safe measurement of large currents, often in the presence of high voltages. The current transformer safely isolates measurement and control circuitry from the high voltages typically present on the circuit being measured.

Comparing with the traditional core material, such as silicon steel and permalloy, Iron based nanocrystalline alloy takes the advantage of high permeability and low cost, it is more competitive in the application of precision current transformer with 0.2,0.2s,0.1 accuracy class, Bushing current transformer for Epoxy resin cast, Gas insulated or oil-immersed switchgears, LV, MV and HV switchgear, and other apparatus in electric power transmission and distribution system 

2. Advantages of nanocrystalline alloy core

 High permeability lead to minimized current measuring error in CT

 High saturation Induction lead to small size and light weight compared to Permalloy CT

 Excellent thermal stability work at -55--130oC for long time

 Low cost Ideal for substitute of permalloy cores commercially.
