Split Core CT Current Transformers

Split Core CT Current Transformer

Split core current transformers have interleaved joint and hinge structure.
Split core CTs have a removable section, so that they can be installed without interrupting the circuit.

A split core current transformer for coupling monitoring apparatus to a current carrying conductor includes a two-piece annular core structure formed by first and second arcuate core assemblies having windings, connectable to the monitoring apparatus, wound on laminated core sections, the laminated core sections each including a plurality of flat lamination elements arranged in a stacked configuration with alternate elements having generally circular end portions which project beyond the main body portion of the arcuate core section at each end thereof defining generally circular gaps....
