Section 11
Testing functionality by secondary injection
Evaluation of the results from the disturbance recording function requires access to a PC either
permanently connected to the IED or temporarily connected to the Ethernet port (RJ-45) on the front. The
PCM600 software package must be installed in the PC.
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.
11.1.4

Event recorder (ER) and Event list (EL)

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.
11.2 Identifying the function to test in the technical reference
manual
Use the technical manual to identify function blocks, logic diagrams, input and output signals, setting
parameters and technical data.
