Disturbance upload can be performed by the use of PCM600 or by any third party tool with IEC
61850 protocol. Reports can automatically be generated from PCM600. Disturbance files can be
analyzed by any tool reading Comtrade formatted disturbance files.
It could be useful to have a printer for hard copies. The correct start criteria and behavior of the
disturbance recording function can be checked when IED protective functions are tested.
When the IED is brought into normal service it is recommended to delete all recordings, made during
commissioning to avoid confusion in future fault analysis.
All recordings in the IED can be deleted in two ways:
1.
in the local HMI under
Main menu/Clear /Reset disturbances
, or
2.
in the Disturbance handling tool in PCM600 by selecting
Delete all recordings in the IED...
in the
window
Available Recordings in IED
.
10.1.4
Event recorder (ER) and Event list (EL)
M12645-2 v7
The result from the event recorder and event list can be viewed on the local HMI or, after upload, in
PCM600 as follows:
1.
on the local HMI under
Main menu/Events
, or in more details via
2.
the
Event Viewer
in PCM600.
The internal FIFO register of all events will appear when the event viewer is launched.
When the IED is brought into normal service it is recommended to delete all events resulting from
commissioning tests to avoid confusion in future fault analysis. All events in the IED can be cleared in
the local HMI under
Main Menu//Clear/Clear internal event list
or
Main menu /Clear/Clear
process event list
. It is not possible to clear the event lists from PCM600.
When testing binary inputs, the event list (EL) might be used instead. No uploading or analyzing of
registrations is then needed since the event list keeps running, independent of start of disturbance
registration.
10.2
Identifying the function to test in the technical
reference manual
M11748-2 v4
Use the technical manual to identify function blocks, logic diagrams, input and output signals, setting
parameters and technical data.
10.3
Differential protection
IP10805-1 v1
10.3.1
Restricted earth fault protection, low impedance REFPDIF
SEMOD55252-82 v8
Prepare the IED for verification of settings outlined in Section
"Preparing the IED to verify settings"
Logical signals for REFPDIF protection are available on the local HMI under
Main menu /
Settings /IED Settings /Differential protection /LowImpREF(87N, IdN/I) /REFPDIF (87N; IdN/
I):x
, , where x = 1 and 2.
The Signal Monitoring in PCM600 shows the same signals that are available on the local HMI.
