Identification of gradual failure time-frequency feature in fiber optical current transformer

Decomposing the output signal of fiber optical current transformer (FOCT) with time-frequency conversion is the key step to obtain the gradual fault characteristics. Aiming at the characteristics of FOCT gradual fault signal with large time domain span and random deterioration process,the output sig...
