Discrete wavelet transform based approach for current transformer saturation problem

open access: yes2009 IEEE 17th Signal Processing and Communications Applications Conference, 2009
This work is about the possible effects of protection devices and schemes during current transformer saturation. If current transformer specifications are not selected properly, saturation may occur and affect relay response or even fail to trip. Hence, the performance of the protection devices such as differential and impedance relays is mainly based ...

The Impact of Current-Transformer Saturation on Transformer Differential Protection

IEEE Transactions on Power Delivery, 2015
Current-transformer (CT) saturation has a major impact on the operation of differential protection schemes. Transformer differential protection must maintain security during CT saturation for external faults while preserving high sensitivity and speed of operation for lower magnitude internal faults.

Current-Transformer Saturation Compensation for Transformer Differential Relays

IEEE Transactions on Power Delivery, 2015
Current-transformer (CT) saturation threatens accurate discrimination between internal fault current and magnetizing inrush current of a transformer and endangers the proper operation of a differential relay. Thus, compensation of CT saturation could substantially improve the performance and security of transformer differential relays.
