Logical Nodes
The following tables, Table F.20 through Table F.24, show the Logical Nodes
(LN) supported in the SEL-751 and the associated Relay Word bits or
measured quantities. Table F.20 shows the LN associated with protection
elements defined as Logical Device PRO.
Data Objects
Status Information
ColOpn SPS Open command of trip coil M
Measured Values
AbrPrt MV Calculated or measured wear (e.g. of main contact), expressed in % where
0% corresponds to new condition
E
a
Transient data objects—the status of data objects with this designation is momentary and must be logged or reported to provide evidence
of their momentary state.
