There are several types of current transformers (CTs) in use today. The frequency of the current distinguishes them they are designed to measure, the method of connection to the circuit being calculated, the number of secondary windings, the turns ratio, and the core material. This blog post will take a closer look at the different types of current transformers and their applications.
How Many Types Of Current Transformers?
There are two main types of current transformers: the wound type and the toroidal type. The wound type has a primary winding wrapped around the secondary winding. The toroidal type has a primary winding that is wrapped around a core of ferrite material.
Different Types Of Current Transformers
A wound-type current transformer (WCT) is a current transformer used to measure alternating current (AC). It consists of a primary winding, typically a coil of wire, and a secondary winding. The primary winding is wound around the secondary winding, and the two are connected in series.
WCTs are used in various applications, such as measuring the current in a power line or monitoring the current in an electrical system.
A toroidal type current transformer is an electrical device used to measure alternating current (AC). It is designed so that the primary winding is wound around a ring-shaped core, while the secondary winding is wound around the same core but in the opposite direction. This design allows for a more efficient transformer as there is less leakage of the magnetic field.
Toroidal type current transformers are used in various applications, such as in electrical meters and protection devices.
Which Type Of Current Transformer Is Best For Your Application?
It depends on your specific needs. If you need a high degree of accuracy, the wound type is the better choice. The toroidal type is the better choice if you need a lower degree of accuracy and a lower price.
In conclusion, there are two main types of current transformers: the wound and toroidal types. Each has its advantages and disadvantages. For more information on current transformers, visit us at Laxmi Associates.
