Besides this, information ondistance to fault is very important for those involved in operation and maintenance.Reliable information on the fault location greatly decreases the downtime of theprotected lines and increases the total availability of a power system.The fault locator is started with the input CALCDIST to which trip signalsindicating in-line faults are connected, typically distance protection zone 1 andaccelerating zone or the line differential protection. The disturbance report mustalso be started for the same faults since the function uses pre- and post-faultinformation from the trip value recorder function (TVR).Beside this information the function must be informed about faulted phases forcorrect loop selection (phase selective outputs from differential protection, distanceprotection, directional OC protection, and so on). The following loops are used fordifferent types of faults:Section 15 1MRK 505 393-UEN BMonitoring344 Line differential protection RED650 2.2 IECApplication manual
