Types of Current Transformers
Following are the Types of Current Transformers
- Indoor Current Transformers
- Outdoor Current Transformers
- Bushing Current Transformers
- Portable Current Transformers
Indoor Current Transformers
Current Transformers Which Designed For Indoor Environments are Known as Indoor current Transformers. They Have Very Compact Size which can used by Indoor Equipments for Medium to low Voltage Utilization. Indoor Current Transformers Have good Insulation with high Accuracy which makes theme Suitable for Indoor Environments.
Examples of Current Transformers are:
- Bar-Type CT: CT which has rectangular or circular type primary winding instead of traditional coil or winding.
- Ring Type: These are CT where slot or space is left in the centre to accommodate the primary conductor.
- Wound Type CT: In this CT the primary winding has multiple turns.
Outdoor Current Transformers
Outdoor current transformers are those that are specifically made to endure weather-related conditions and are engineered to survive elements like rain and UV radiation. They are commonly utilized for medium to high outdoor equipment. Outdoor current transformers provide accurate measurements even in challenging outdoor conditions.
Examples are:
- Mining CTs: These Types of CTs are specially designed for the mining areas.
- Railway Electrification CTs: They are designed for outdoor railway electrification systems.
- Switchyard CTs: These CTs are used in Switchyard for current measuring and monitoring purposes.
Bushing Current Transformer
Current Transformers which are desgined in form of bushing are known as Busing Current Transformers.They are Mounted on the buishing of the Equipment which make them compact and integral part of the overall system.They are used for relaying and measuring existing power transformers or circuit breakers.
Portable Current Transformers
As the name Suggest these types of Current Transformers are designed to be easily movable and are mostly used for temporary electrical measurments and Testing. They are Very much Flexible and used where Permanent Transformers Canoot be Installed.
