Monitoring
When an input is set, the respective output is set for a user defined time. If the input signal
remains set for a longer period, the output will remain set until the input signal resets.

Setting guidelines
The pulse time
can be set or reset individually, but the pulse time will be the same for all outputs in the entire
BINSTATREP function.

Function description
Fault locator
17.8.2
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, directional OC
protection, and so on). The following loops are used for different types of faults:
•
for 3 phase faults: loop A-B.
•
for 2 phase faults: the loop between the faulted phases.
•
for 2 phase-to-ground faults: the loop between the faulted phases.
•
for phase-to-ground faults: the phase-to-ground loop.
