management of user accounts, roles and certificates and the distribution of such, a procedurecompletely transparent to the user.The Flexible Product Naming allows the customer to use an IED-vendor independent 61850model of the IED. This customer model will be used as the IEC 61850 data model, but all otheraspects of the IED will remain unchanged (e.g., names on the local HMI and names in the tools).This offers significant flexibility to adapt the IED to the customers system and standardsolution2.2 Main protection functions GUID-66BAAD98-851D-4AAC-B386-B38B57718BD2 v12Table 2: Example of quantities2 = number of basic instances0-3 = option quantities3-A03 = optional function included in packages A03 (refer to ordering details)IEC 61850 ANSI Function description TransformerRET650 (A05)Differential protectionT3WPDIF 87T Transformer differential protection, three winding 1REFPDIF 87N Restricted earth fault protection, low impedance 22.3 Back-up protection functions GUID-A8D0852F-807F-4442-8730-E44808E194F0 v11IEC 61850 ANSI Function description TransformerRET650 (A05)Current protectionPHPIOC 50 Instantaneous phase overcurrent protection 1OC4PTOC 51_671) Four step phase overcurrent protection 3EFPIOC 50N Instantaneous residual overcurrent protection 1EF4PTOC 51N67N2)Four step residual overcurrent protection 2SDEPSDE 67N Sensitive directional residual overcurrent andpower protectionTRPTTR 49 Thermal overload protection, two time constant 1CCRBRF 50BF Breaker failure protection 3GUPPDUP 37 Directional underpower protectionGOPPDOP 32 Directional overpower protectionBRCPTOC 46 Broken conductor checkLOVPTUV 27 Loss of voltage checkMultipurpose protectionCVGAPC General current and voltage protection 31) 67 requires voltage2) 67N requires voltageSection 2 1MRK 504 158-UEN AApplication20Application manual
