<p class="Abstract"><span lang="EN-US">Analysis of transients in longitudinal differential protection schemes is given basing on results obtained by simulation. Simulation diagram for modeling differential protection with current transformers with non-linear cores is proposed. Main shortcomings of using current transformers as measuring transducers are shown. Solutions of the problem revealed are proposed. </span></p>
