Transformer Differential Protection Setting Calculations
courseware.cutm.ac.inDifferential Protection Setting Calculations Where R CT is CT burden (internal) R W total resistance of the ct secondary wiring. R R is relay burden V S = I (R CT + R W + R R) Where I is the fault current and V S is the ct secondary voltage. In order to make sure that the ct is in the linear range (to avoid ac saturation of the ct’s), V
