What are the types of current transformers?
Current transformers (CTs) are classified into different types based on their construction and application. The main types include:
Bar type current transformers: These CTs have a primary conductor passing through the core, usually in the form of a solid bar. They are typically used for high current applications and provide high accuracy for measuring large currents.
Toroidal Current Transformers: These CTs have a ring-shaped core through which the primary conductor passes. They are often used for low current applications and can measure current without the need to break the circuit.
Wound Type Current Transformers: These CTs have a primary winding wound around the core and are used for lower current measurements. They are often used in applications where precise measurement is required.
Clamp Current Transformers: These CTs can be attached around a conductor to measure current without disconnecting the circuit. They are suitable for portable and non-intrusive measurements.
Instrument Current Transformers: These CTs are designed to provide accurate measurements for instrumentation and protection systems. They are used in measurement and monitoring applications where high accuracy is essential.
The number of current transformer types may vary depending on specific applications and designs. Generally, types are classified based on their basic construction, primary winding, and application requirements.
Current transformers are devices used to measure and monitor high currents by producing a proportionally lower current that can be safely measured by standard instruments. They operate by passing a high current through a primary winding or core, inducing a proportionally lower current in the secondary winding.
When choosing a current transformer, consider the following factors:
Current ratio: The CT must match the expected primary current and provide an appropriate secondary current for the measurement.
How many types of current transformers are there?
Precision Class: Select a CT with the accuracy required for your application.
Load: Make sure the CT can handle the load of connected measuring instruments.

Physical Size and Installation: Choose a CT that fits the installation space and meets the physical requirements of the application.
A “600/5” current transformer means that the CT is designed to produce a secondary current of 5 amps when the primary current is 600 amps. This ratio allows precise scaling of high primary currents to a manageable level for measurement and monitoring purposes.
