Applications

Current transformer of power system pla短友ys an important role in providing a朋喝 current in its secondary winding p個和roportional to the alternating curre多下nt flowing in its primary. They are c鐵頻ommonly used in meter房畫ing and protective relaying in the po短土wer plants and substat子厭ions where they facilitate the sa場時fe measurement of large currents, o市雜ften in the presence of high voltages腦民. The current transformer safely isol分少ates measurement and control cir暗月cuitry from the high 街人voltages typically present on the街我 circuit being measured.

Comparing with the traditional core mat爸拿erial, such as silicon steel and per樂文malloy, Iron based nanocrystalline a場水lloy takes the advantage of high per放草meability and low cos那少t, it is more compet區街itive in the application of precision c是畫urrent transformer w呢這ith 0.2,0.2s,0.1 accuracy cla多開ss, Bushing current transformer for 謝電Epoxy resin cast, Gas insulat師但ed or oil-immersed s吧什witchgears, LV, MV and HV媽男 switchgear, and other apparatus近亮 in electric power transmissio做麗n and distribution system.
