Section 9
Testing functionality by secondary injection
All recordings in the IED can be deleted in the Disturbance handling tool in PCM600 by selecting
Delete all recordings in the IED... in the window Available Recordings in IED.
9.1.4
Event recorder (ER) and Event list (EL)
The result from the event recorder and event list can be viewed using Event Viewer in PCM600. The
internal FIFO register of all events will appear when the event viewer is launched.
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.
9.2
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.
9.3
Control
9.3.1
Apparatus control APC
The apparatus control function consists of four types of function blocks, which are connected in a
delivery-specific way between bays and to the station level. For that reason, test the total function in
a system, that is, either in a complete delivery system as an acceptance test (FAT/SAT) or as parts of
that system.
9.4
Logic
9.4.1
Tripping logic, common 3-phase output SMPPTRC
Prepare the IED for verification of settings outlined in Section
This function is functionality tested together with other protection functions (line differential protection,
earth-fault overcurrent protection, and so on) within the IED. It is recommended that the function is
tested together with the autorecloser function, when built into the IED or when a separate external
unit is used for reclosing purposes.
9.4.1.1
Three-phase operating mode
1.
Check that AutoLock and TripLockout are both set to Off .
2.
Initiate a three-phase fault.

If a block/unblock command is sent from remote to function, while the IED is shut down,
this command will not be recognized after the start up, thus the command that was sent
prior to the shut down is used. In such cases, where there is a mismatch, the user is
advised to make a complete cycle of block/unblock operations to align the statuses.
The complete apparatus control function is not included in this product.
