DISCRETE WAVELET TRANSFORM BASED APPROACH for CURRENT TRANSFORMER SATURATION PROBLEM

2022
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 ...
