Construction of the Current Transformer
Current Trasnformer
The figures presented illustrate the construction of the current transformer, featuring a design similar to a typical transformer with two windings: Primary and Secondary Similar to a standard transformer, the input is taken from the primary winding, while the output is obtained from the secondary winding. The primary winding has one or more turns of heavy cross-sectional area wire (also called bar-primary). The secondary winding, on the other hand, has a large number of fine wires with less cross-sectional area wrapped around the core. The primary and secondary windings are isolated from each other. The core of the transformer is made of ferromagnetic material, similar to the standard transformer, such as iron or laminated cores. They are used because of their ability to efficiently concentrate the magnetic field. The output is connected to measuring instruments, relays, or other monitoring devices.
