Cast Ring Type Current Transformers

Cast Ring Type Current Transformers are used to measure alternating current in electrical systems. They are typically used in high-voltage applications, such as in power distribution systems, to measure the current in a circuit. These transformers consist of a ring-shaped core of magnetic material, such as iron or ferrite, with two or more windings of insulated copper wire wound around it. The primary winding is connected in series with the circuit whose current is to be measured, while the secondary winding is connected to the measuring instrument. When current flows through the primary winding, these Cast Ring Type Current Transformers induce a magnetic field in the core, which in turn induces a voltage in the secondary winding. This voltage is proportional to the current flowing in the primary winding, and can be used to measure the current in the circuit.
