- Dec 04, 2020-

According to different purposes, Electrical Current Transformer can be roughly divided into two categories: Electrical Current Transformer for measurement (or measurement winding of Electrical Current Transformer): Provides current information of the power grid to measurement and metering devices within the normal working current range. Electrical Current Transformer for protection (or protection winding of Electrical Current Transformer): Provides grid fault current information to relay protection and other devices under grid fault conditions.
