Section 12
Monitoring
contain up to 1000 events from both internal logic signals and binary input channels. If the list is full,
the oldest event is overwritten when a new event arrives.
The list can be configured to show oldest or newest events first with a setting on the local HMI.
The event list function runs continuously, in contrast to the event recorder function, which is only
active during a disturbance.
The name of the binary signal that appears in the event recording is the user-defined name assigned
to the corresponding input of the BxRBDR function. The same name is used in the disturbance
recorder function , indications and the event recorder function .
The event list is stored and managed separate from the disturbance report information .

Trip value recorder

12.8.1

Functionality

Information about the pre-fault and fault values for currents and voltages are vital for the disturbance
evaluation.
The Trip value recorder calculates the values of all selected analog input signals connected to the
Disturbance recorder function. The result is magnitude and phase angle before and during the fault
for each analog input signal.
The trip value recorder information is available for the disturbances locally in the IED.
The trip value recorder information is an integrated part of the disturbance record (Comtrade file).
12.8.2

Function block

The Trip value recorder has no function block of its own.
12.8.3

Signals

12.8.3.1

Input signals

The trip value recorder function uses analog input signals connected to A1RADR to A3RADR (not
A4RADR).
