The article aims to study the change of instantaneous values of differential current in power transformer protection circuits during magnetizing inrush when the unloaded transformer is connected to a power source and when a fault occurs in the protected area. Also, time behavior of the unbalance current in the generator, differential protection during remote faults is considered. Saturation of measuring current transformers during the fault transients leads to distortion of signals in theirdoi:10.2991/aime-17.2017.69 fatcat:kzqnu3aggzerzmecsz43mrph2u
