Split-Core Type Transformer for AC Currents

Technical data and functions

How Split-Core Type Transformers Work

Current transformers are used to acquire high alternating currents without contact and without interrupting the circuit. In principle, they consist of 2 separate transformator windings (B₁ = primary winding with N₁ windings, B₂ = secondary winding with N₂ windings) on one common iron core (closed magnetic circuit).
If an alternating current I₁ flows through the winding B₁, a current I₂ is induced in the winding B₂, which depends on the winding ratio N₁/N₂. In comparison with stationary-installed panel transformers, split-core type transformers must be able to embrace a conductor within a magnetic circuit that is split open.
In practice, the primary winding B₁ consists of only one winding that carries the current to be measured.

The transformation ratio of a current transformer is: I₁ x N₁ = I2 x N2
