How does a split core current transformer work

FAQ | Feb 15,2023

The working principle of Split core current transformer is the same as normal current transformers.  When the flow of AC current in the primary winding generates an alternating magnetic field in the magnetic core which then mutually induces an alternating current in the secondary winding.

The processes occurring inside the current transformer can be grouped into two:Magnetic flux is produced in a coil when ever there is a change in current flowing through the coil. Similarly change in magnetic flux linked with the coil induces EMF in the coil. The first process occurs in the windings of the current transformer. When the ac supply is given to the primary winding alternating flux is produced in the coil .The second process occurs in the secondary winding of the current transformer. The flux alternating flux produced in the current transformer links the coils in the secondary winding and hence emf is induced in the secondary winding. Whenever an ac supply is given to the primary coil, flux is produced in the coil. These flux links with the secondary winding thereby inducing emf in the secondary coil.
