Feature:
*High ui .for supreme accuracy up to 0.1S class
*High Bs. For bigger current detection range than permalloy cores.
*Low Hc. for high permbeablity stability.
* Various core construction.(Type: toroidal, Rectangular, track
* Various capsulated options.(plastic case, stainless steel case+epoxy potting, epoxy coating crepe paper winding,etc)
*Excellen permeablity Vs temperature stability.
*Operating temperature range: －５０~+130℃.
?
Application:
* Current transfomer for Watt-hour meters.
* Current transfomer for metering and relaying.
* Current transformers for high/medium /low voltage switch gears
* Current transformers for Motors control panels.
* Data sampling for current and voltage.
