Verifying Analog Primary And Secondary Measurement - ABB Relion 670 Series Commissioning Manual

1MRK 511 403-UEN Rev. K
through every function to ensure that only the function to be tested (and the interconnected ones)
have the parameters Blocked and eventually EvDisable set to No and Yes respectively. Remember
that a function is also blocked if the BLOCK input signal on the corresponding function block is
active, which depends on the configuration. Ensure that the logical status of the BLOCK input signal
is equal to 0 for the function to be tested. Event 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 EvDisable to Yes.
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 Blocked for the selected function to No.

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.
Besides verifying analog input values from the merging unit via the IEC/UCA 61850-9-2LE process
bus, analog values from the transformer input module can be verified as follows.
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

Commissioning manual
Any function is blocked if the corresponding setting in the local HMI under Main
menu /Test /Function test modes menu remains On, that is, the parameter
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 Test mode is set to On, are reset when a
new test mode session is started.
Apply input signals as needed according to the actual hardware and the application
configuration.
If the IEC/UCA 61850-9-2LE communication is interrupted during current injection,
the disturbance report tool in PCM600 will display the current that was injected
before the interruption.
