3.5.7 GE namespace
The GE namespace is an extension of the "IEC 61850-7-4:2007A" namespace, and as such includes by reference all data
object names in IEC 61850-7-4 Edition 2.0 2010-03. As these names are defined in the standard, they are not described in
this document. The GE namespace schema file "GEExtensionsV1_0.xsd" is located in the same folder as the UR EnerVista
software installation, for example in C:\Program Files (x86)\GE Power Management\URPC\GESchema\
The name of the GE namespace specified for firmware 7.4x in this document is "GE Multilin UR Namespace:2015A"
In the last column, the logical node number is not included. For example, LPHD refers to LPHD1.

AaDmd MV Phase A demand.
SRC 1 DMD IA, in primary amperes.
DmdMtrMMTR
AaMaxDmdDt MV Phase A Max Demand with Date (time stamp). The ClcMth cannot be used for
MAX, as the time stamp definition of IEC 61850 is different from UR.
SRC 1 DMD IA MAX, in primary amperes with associated date, SRC 1 DMD IA DATE.
DmdMtrMMTR
AaRMS MV Phase A current RMS.
SRC 1 Phase A Current RMS, in primary amperes.
ACsrcMMXU
AbDmd MV Phase B demand.
SRC 1 DMD IB, in primary amperes.
DmdMtrMMTR
AbMaxDmdDt MV Phase B Max Demand with Date (time stamp). The ClcMth cannot be used for
MAX, as the time stamp definition of IEC 61850 is different from UR.
SRC 1 DMD IB MAX, in primary amperes with associated date, SRC 1 DMD IB DATE.
DmdMtrMMTR
AbRMS MV Phase B current RMS.
SRC 1 Phase B Current RMS, in primary amperes.
ACsrcMMXU
AcDmd MV Phase C demand.
SRC 1 DMD IC, in primary amperes.
DmdMtrMMTR
AcMaxDmdDt MV Phase C Max Demand with Date (time stamp). The ClcMth cannot be used for
MAX, as the time stamp definition of IEC 61850 is different from UR.
SRC 1 DMD IC MAX, in primary amperes with associated date, SRC 1 DMD IC DATE.
DmdMtrMMTR
AcRMS MV Phase C current RMS.
SRC 1 Phase C Current RMS, in primary amperes.
ACsrcMMXU
Activated SPS Activated. In this logical node, indicates position of a pushbutton. When "true", the
pushbutton is asserted state; when "false", the pushbutton is in a released state.
CONTROL PUSH BUTTON 1 ON operand.
PUSHBUTTON 1 ON operand.
CtlPshIHMI, UsrPbIHMI
Adif CMV Differential current (sum of the three phase currents and the ground (fourth)
current. Restricted ground differential if the fourth current measures the ground
current in a grounded wye winding. Measures CT secondary circuit trouble if
fourth current measures the CT secondary neutral current.
SRC 1 Differential Ground Current phasor, in primary volts.
