In the case of bushing-type current transformers, the customer’s primary wire is pushed
through the current transformer opening in the housing. The push-through opening depends
on the size of the primary current.
Wound primary type current transformers have a primary winding and a secondary winding.
Both windings are applied on the closed toroidal core and are isolated from each other by
insulation. This principle applies mainly where primary currents are small. Low-voltage current
transformers for the proportional transformation of large currents to directly measurable
smaller current values
