Selection of Current Transformers for Relay Protection
This article focuses on practical deployment: how CTs feed protective relays, how to select and size CTs for different protection schemes, common installation and testing practices, and how modern sensor technologies change protection design. Current transformers (CTs) are the primary sensing interfaces between high-current power circuits and the low-voltage protection and metering equipment used in substations and transmission networks. Correct CT selection and application directly influence: Billing accuracy: Misapplied ratio or accuracy class can cause revenue leakage or disputes.
