Applications

Current transformer of power syste都國m plays an important role會雪 in providing a current in i可現ts secondary winding proportio紅遠nal to the alternating curr哥空ent flowing in its prim暗女ary. They are commonly used in meter媽照ing and protective relaying in the就理 power plants and substations where 音業they facilitate the safe measurement o裡妹f large currents, often in the presen公腦ce of high voltages. The cur信國rent transformer safely isolates measur路農ement and control circuitry from the 他事high voltages typically p拍都resent on the circui為文t being measured.

Comparing with the traditional co街務re material, such as silicon stee筆西l and permalloy, Iro線些n based nanocrystalline allo裡子y takes the advantage of high制機 permeability and low cost, it is場空 more competitive in the application of科都 precision current trans朋暗former with 0.2,0.2s,0.1 accuracy class物話, Bushing current transforme謝湖r for Epoxy resin cast, Gas insulate店地d or oil-immersed swi刀弟tchgears, LV, MV and HV switchgea遠民r, and other apparatus 厭綠in electric power transmission and 有得distribution system.

      Antainano®鐵芯具有高磁導率、精度高。與坡莫合金(jīn)相比具有雨個更高的飽和磁通密度，測量電流範圍更廣。

    Advantages of nanocr友銀ystalline alloy core

• High permeability―le對上ad to minimized current measuring er如離ror in CT
• High saturati朋匠on Induction ―lead to small 市公size and light weight compared to路們 Permalloy CT
• Excellent thermal stab信會ility―Can work at -55~130°C 信購for long time
• Low cost:Idea她木l for substitute of per好自malloy cores commercially
