Disturbance recorder

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 recorder 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 9,9 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.

Function block

The Disturbance recorder has no function block of it's own.
