Disturbance report - Introduction
The Fault locator contains information about the distance to the fault and
about which measuring loop that was selected for the calculation. After
changing the system parameters in the protection, a recalculation of the
fault distance can be made in the protection. See "Fault locator", in
"1MRK 580 138-XEN".
Trip values includes phasors of currents and voltages before the fault and during
the fault. See "Measurement of alternating quantities", 1MRK 580 159-XEN.
The Disturbance recorder registers analogue and binary signal data before,
during, and after the fault. See "Disturbance recorder", in "1MRK 580 141-
XEN".
On the built-in MMI, the indications, the fault locator result (when appli-
cable), and the trip values are available. For a complete Disturbance
Report, front communication with a PC or remote communication with
SMS is required.
