( ) 100sIN I IBase IECEQUATION17003 V1 EN (Equation 191)Transformer inrush current shall be considered.The setting of the protection is set as a percentage of the base current (IBase).Operation: set the protection to On or Off.IN>>: Set operate current in % of IB.IN>>Max and IN>>Min should only be changed if remote setting of operationcurrent level, IN>>, is used. The limits are used for decreasing the used range of theIN>> setting. If IN>> is set outside IN>>Max and IN>>Min, the closest of the limitsto IN>> is used by the function. If IN>>Max is smaller than IN>>Min, the limits areswapped.StValMult: The set operate current can be changed by activation of the binary inputENMULT to the set factor StValMult.9.4 Directional residual overcurrent protection, four stepsEF4PTOC9.4.1 IdentificationFunction description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberDirectional residual overcurrentprotection, four stepsEF4PTOC 4(IN>)4 alt4TEF-REVA V2 EN51N_67N9.4.2 ApplicationThe directional residual overcurrent protection, four steps EF4PTOC is used inseveral applications in the power system.
