An instance specific clear option is provided to delete all the through fault reports from local
HMI.
Through fault monitoring report handling
GUID-049E8C44-B981-4731-9882-0402AC57C17D v1
The through fault monitoring creates fault report for each through fault event. The through
fault information is stored in a zipped .xml file in the IED under flash/frep folder. Each instance
can have maximum 100 reports. Information in the through fault report is grouped into four
sections; the general section and other three sections containing individual winding and
phase-wise through fault data. The outputs given as ‘general data’ and ‘winding wise for all
phases’ in the through fault monitoring report are shown in
.

In case of 2-winding transformers:
•
The Winding 3 section is excluded from the report
•
The Winding 3 information under general section will have zero values
Each report is created with a unique identifier. For example, the second through fault report of
the first instance will have report identifier as
frep_1_2.zip
. The first digit in the identifier
indicates the instance number and the second digit represents the report number.
The through fault report can be read using the FTP client, PCM600 tool or via IEC61850 MMS
file transfer.

Clearing and acknowledging via the local HMI
GUID-9880CE57-79DE-4949-B9FA-1E91ED2F5F4B v5
Use the Clear button to reset, acknowledge or clear all messages and indications, including
LEDs and latched outputs as well as registers and recordings. Pressing the Clear button
activates a view for selecting the reset function. Events and alarms assigned to alarm LEDs can
also be cleared with the Clear button.
