Before discussing anything about a current transformer, first we must know what is an AC transformer? An AC transformer is a static device that is used to transfer electrical energy between two or more circuits through electromagnetic induction. A current transformer is a type of transformer that is used to measure alternating current (AC). It is used in electricity meters and protective relays.
A current transformer steps down the current to a manageable level so that it can be fed into the meter or relay without affecting it. The primary winding of the Current Transformer is connected in series with the conductor through which the current to be measured flows.
What is a current transformer?
A current transformer is a type of transformer that is used to measure alternating current (AC). It is used in electronic equipment to measure currents up to several thousand amps. Current transformers are also used to stepped-down high voltages so that they can be safely measured by low voltage instruments.
Different types of current transformers
There are various types of current transformers used in different applications. The most common types are:
1. Air core CTs: These are the simplest form of CTs and are used in low-power applications. They consist of a coil of wire wound around an iron core. The primary and secondary windings are placed in series with the load.
2. Iron core CTs: These are more efficient than air core CTs and are used in high-power applications. They consist of a coil of wire wound around an iron core. The primary and secondary windings are placed in series with the load.
3. Rogowski CTs: These are used for measuring alternating current (AC). They comprise a conductor which is wrapped around a non-magnetic former. The Rogowski coil has no magnetic cores, which makes it lightweight and easy to carry.
4. Hall effect CTs: These utilize the Hall Effect to measure DC or low-frequency AC currents. A conductive plate is placed in a magnetic field and a voltage is generated perpendicular to the direction of the current flow and the magnetic field strength.
Conclusion
A current transformer is a type of transformer that is used to measure alternating currents. It is typically used in electrical transmission and distribution systems. Current transformers are available in a variety of shapes and sizes, and their primary function is to provide isolation between the measuring instrument and the high-voltage circuit.
