Functionality
To get fast, condensed and reliable information about disturbances in the primary and/
or in the secondary system it is important to know, for example binary signals that
have changed status during a disturbance. This information is used in the short
perspective to get information via the local HMI in a straightforward way.
There are three LEDs on the local HMI (green, yellow and red), which will display
status information about the IED and the Disturbance recorder function (triggered).
The Indication list function shows all selected binary input signals connected to the
Disturbance recorder function that have changed status during a disturbance.
