GlobalBaseSel: Selects the global base value group used by the function to define
(IBase), (UBase) and (SBase).
12.13.6 Operation principle
The input signal must be connected to a range output of a measuring function block
(CVMMXN, CMMXU, VMMXU, VNMMXU, CMSQI, VMSQ or MVGGIO). The
function block converts the input integer value to five binary output signals according
to
table 405.

12.14.2 Functionality
The Fault locator LMBRFLO in the IED is an essential complement to other
monitoring functions, since it measures and indicates the distance to the fault with
great accuracy. It indicates the distance to fault in kilometers or miles as selected by
parameter setting.
The fault locator LMBRFLO function, supports kilometer and mile
for the line length unit. The fault distance will be presented with the
same unit as the line length and is mapped to IEC61850 -8-1
communication protocol, where the fault distance is supposed to be in
kilometer (km). Select the line length unit to kilometer for compliance
with IEC61850.
