Split Core 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.
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....

Defination of Split-Core CT Current Transformers
Just like the
typical current transformer,
the split-core current transformer measures alternating current flowing through a conductor.
