CORE / Wound Toroidal Cores / Permalloy Cores
It is a core wound in a toroidal shape by stripping a material with high investment rate (Ni80%, thickness 0.07~0.1mm) and is mainly used as a CT core of a large-capacity ZCT core and an electronic wattmeter as the non-error rate and phase angle are close to zero even in a low current region (100mA).
