18.7.3 Setting guidelines
The pulse time t is the only setting for the Logical signal status report (BINSTATREP).
Each output can be set or reset individually, but the pulse time will be the same for all
outputs in the entire BINSTATREP function.

18.8.2 Application
The main objective of line protection and monitoring IEDs is fast, selective and reliable
operation for faults on a protected line section. Besides this, information on distance to
fault is very important for those involved in operation and maintenance. Reliable
information on the fault location greatly decreases the downtime of the protected lines and
increases the total availability of a power system.
The fault locator is started with the input CALCDIST to which trip signals indicating in-
line faults are connected, typically distance protection zone 1 and accelerating zone or the
line differential protection. The disturbance report must also be started for the same faults
since the function uses pre- and post-fault information from the trip value recorder
function (TVR).
Beside this information the function must be informed about faulted phases for correct
loop selection (phase selective outputs from differential protection, distance protection,
