( ) 100sIN I IBase IECEQUATION17003 V1 EN-US (Equation 111)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 ofthe IN>> setting. If IN>> is set outside IN>>Max and IN>>Min, the closest of thelimits to IN>> is used by the function. If IN>>Max is smaller than IN>>Min, thelimits are swapped.StValMult: The set operate current can be changed by activation of the binary inputENMULT to the set factor StValMult.8.4 Directional residual overcurrent protection, foursteps EF4PTOC IP14509-1 v88.4.1 IdentificationM14881-1 v6Function description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberDirectional residual overcurrentprotection, four stepsEF4PTOC 4(IN>)4 alt4TEF-REVA V2 EN-US51N_67N8.4.2 Application M12509-12 v10The directional residual overcurrent protection, four steps EF4PTOC is used inseveral applications in the power system.
