How many types of CT transformers are there?
Based on Application:
Protection CTs: Designed to accurately measure fault currents and provide inputs to protective relays to isolate faulty sections of power systems.Metering CTs: Used for accurately measuring currents in power systems for billing and monitoring purposes.
Based on Construction:
Bar-type CTs: These are cylindrical in shape and can be installed around the conductor to be measured.Window-type CTs: These have a split core construction, allowing them to be installed around the conductor without disconnecting it.
Based on Accuracy:
Revenue Grade CTs: These are highly accurate and are used for billing purposes.Protection Grade CTs: These provide accurate measurements within specified ranges for protection purposes.
Based on Core Material:
Ferrite-core CTs: These use ferrite material as the core, typically for lower frequency applications.Iron-core CTs: These use laminated iron cores and are suitable for higher frequency applications.
Based on Purpose:
Single Ratio CTs: These have a fixed ratio between the primary and secondary currents.Multi Ratio CTs: These have multiple taps on the secondary winding, allowing for different ratios to be selected.
Based on Special Features:
High Frequency CTs: Designed for use in high-frequency applications such as inverter drives or power electronic systems.Wideband CTs: These are designed to accurately measure wideband currents, typically used in communication systems or high-frequency testing.
These categories represent some common ways CT transformers can be classified, but there may be additional types or variations based on specific applications and industry standards.
