Feature:
*High initial permeability for high accuracy and low errors
*High saturation flux density. For Wider current measurement range.
*Low coercive force. for high sensitivity for feeble current signal.
*Excellent thermal stability for permeability for small error shift.
*High curie temperature ,superior temperature performance.
*Long –term working temperature range: -50~+130℃.
Application:
*Watt-hour meters, power meters, ampere meters in instrument industry.
*HVCT, MVCT and LVCT in transmission and distribution system.
*GFCI, protection relay, servo-motors protection, fire monitoring, etc.
*Data sampling for current and voltage.
