As shown in Figure 2.32-7 (shaded portion d), the detail information is displayed along
with the fault determination, which is simplified with notations, Table 2.32-5 summarizes the
notations of fault determination.

Comment
Fault location is assumed over the boundary.In the case of
three-terminal application, the boundary means the sum
of the two line length.
Fault location is assumed over the junction;
this information is applied only for the
data at a local-terminal only
calculation with data at a local-terminal and remote-
terminals
will appear instead like "Sec.1" or "Sec.2".
Since a number of calculation results are scattered, the FL
chooses one of the result value in order that the scattering
turns to be small.
Communication failures are risen while data recording;
hence the
only
is brought for the fault determination. Note that the
result of the calculation decays.
