Applications

Current transformer o去風f power system plays an i草自mportant role in providing a current師少 in its secondary winding p和美roportional to the alternating是師 current flowing in its pr拍女imary. They are commonly used 木算in metering and protect數煙ive relaying in the 秒又power plants and substa工個tions where they facilita舞師te the safe measurement of lar門司ge currents, often in the presence器放 of high voltages. The current tra站錯nsformer safely isolates mea美視surement and control c還做ircuitry from the high弟見 voltages typically pr樂玩esent on the circuit bein道月g measured.

Comparing with the tradi票答tional core material, such as si了藍licon steel and perma木雪lloy, Iron based nanocrystalline alloy 房著takes the advantage of high per自就meability and low cost, it is more c錢森ompetitive in the application of pr風分ecision current transformer with 0.2,0還雨.2s,0.1 accuracy cla答影ss, Bushing current tra金雨nsformer for Epoxy resin 就物cast, Gas insulated o笑什r oil-immersed switchgears, LV, MV a票水nd HV switchgear, and other apparatu你動s in electric power transmission and d個新istribution system.
