Passive Current transformer Series IE modular

closed-loop current transformers


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
