GE Multilin L60 Line Phase Comparison Relay C-3APPENDIX C C.2 SERVER DATA ORGANIZATIONCMMXU data is provided in two forms: instantaneous and deadband. The instantaneous values are updated every time aread operation is performed by a client. The deadband values are calculated as described in IEC 61850 parts 7-1 and 7-3.The selection of appropriate deadband settings for the L60 is described in chapter 5 of this manual.IEC 61850 buffered and unbuffered reporting capability is available in all MMXU logical nodes. MMXUx logical nodes pro-vide the following data for each source:• MMXU1.ST.TotW: three-phase real power• MMXU1.ST.TotVAr: three-phase reactive power• MMXU1.ST.TotVA: three-phase apparent power• MMXU1.ST.TotPF: three-phase power factor• MMXU1.ST.Hz: frequency• MMXU1.ST.PPV.phsAB: phase AB voltage magnitude and angle• MMXU1.ST.PPV.phsBC: phase BC voltage magnitude and angle• MMXU1.ST.PPV.phsCA: Phase CA voltage magnitude and angle• MMXU1.ST.PhV.phsA: phase AG voltage magnitude and angle• MMXU1.ST.PhV.phsB: phase BG voltage magnitude and angle• MMXU1.ST.PhV.phsC: phase CG voltage magnitude and angle• MMXU1.ST.A.phsA: phase A current magnitude and angle• MMXU1.ST.A.phsB: phase B current magnitude and angle• MMXU1.ST.A.phsC: phase C current magnitude and angle• MMXU1.ST.A.neut: ground current magnitude and angle• MMXU1.ST.W.phsA: phase A real power• MMXU1.ST.W.phsB: phase B real power• MMXU1.ST.W.phsC: phase C real power• MMXU1.ST.VAr.phsA: phase A reactive power• MMXU1.ST.VAr.phsB: phase B reactive power• MMXU1.ST.VAr.phsC: phase C reactive power• MMXU1.ST.VA.phsA: phase A apparent power• MMXU1.ST.VA.phsB: phase B apparent power• MMXU1.ST.VA.phsC: phase C apparent power• MMXU1.ST.PF.phsA: phase A power factor• MMXU1.ST.PF.phsB: phase B power factor• MMXU1.ST.PF.phsC: phase C power factorC.2.6 PROTECTION AND OTHER LOGICAL NODESThe following list describes the protection elements for all UR-series relays. The L60 relay will contain a subset of protec-tion elements from this list.• PDIF: transformer instantaneous differential, transformer percent differential• PDIS: phase distance, ground distance• PIOC: phase instantaneous overcurrent, neutral instantaneous overcurrent, ground instantaneous overcurrent, nega-tive-sequence instantaneous overcurrent.• PTOC: phase time overcurrent, neutral time overcurrent, ground time overcurrent, negative-sequence time overcur-rent, neutral directional overcurrent, negative-sequence directional overcurrent
