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.
