13.11.1 Functionality
The Disturbance recorder function supplies fast, complete and reliable information about
disturbances in the power system. It facilitates understanding system behavior and related
primary and secondary equipment during and after a disturbance. Recorded information is used
for different purposes in the short perspective (for example corrective actions) and long
perspective (for example functional analysis).
The Disturbance recorder acquires sampled data from selected analog- and binary signals
connected to the Disturbance report function (maximum 40 analog and 96 binary signals). The
binary signals available are the same as for the event recorder function.
The function is characterized by great flexibility and is not dependent on the operation of
protection functions. It can record disturbances not detected by protection functions. Up to three
seconds of data before the trigger instant can be saved in the disturbance file.
The disturbance recorder information for up to 100 disturbances are saved in the IED and the local
HMI is used to view the list of recordings.
13.11.2 Function block
The Disturbance recorder has no function block of it's own.
13.11.3 Signals
