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.

Fault locator LMBRFLO

Identification

Function description
Fault locator

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, directional OC protection, and so on). The following loops are used for
different types of faults:
