function blocks can also be individually blocked to ensure that no events are reported to a
remote station during the test. This is done by setting the parameter
Procedure
1. Click the Function test modes menu.
The Function test modes menu is located in the local HMI under Main menu/Test/
Function test modes.
2. Browse to the function instance that needs to be released.
3. Set parameter

Verifying analog primary and secondary measurement

Verify that the connections are correct and that measuring and scaling is done correctly. This
is done by injecting current and voltage to the IED.
1. Inject a symmetrical three-phase voltage and current at rated value.
2. Compare the injected value with the measured values.
The voltage and current phasor menu in the local HMI is located under Main menu/
Measurements/Analog primary values and Main menu/Measurements/Analog
secondary values.
3. Compare the frequency reading with the set frequency and the direction of the power.
The frequency and active power are located under Main menu/Measurements/
Monitoring/ServiceValues(MMXN)/CVMMXN:x. Then navigate to the bottom of the list
to find the frequency.
4. Inject an unsymmetrical three-phase voltage and current, to verify that phases are
correctly connected.
If some setting deviates, check the analog input settings under
Main menu/Configuration/Analog modules

Testing the protection functionality

Each protection function must be tested individually by secondary injection.
• Verify operating levels (trip) and timers.
• Verify alarm and blocking signals.
• Use the disturbance handling tool in PCM600 to evaluate that the protection function has
received the correct data and responded correctly (signaling and timing).
• Use the event viewer tool in PCM600 to check that only expected events have occurred.
Commissioning manual
Any function is blocked if the corresponding setting in the local HMI under Main
menu/Test/Function test modes menu remains
Blocked is set to Yes and the parameter TESTMODE under Main menu/
Test/IED test mode remains active. All functions that were blocked or released
in a previous test mode session, that is, the parameter
are reset when a new test mode session is started.
Blocked for the selected function to No .
Apply input signals as needed according to the actual hardware and the
application configuration.
Testing IED operation
EvDisable to Yes .
