Verifying Analog Primary And Secondary Measurement - ABB Relion 650 Series REL650 Commissioning Manual

Section 5
Testing IED operation

Any function is blocked if the corresponding setting in the local HMI
under Main menu/Tests/Function test modes menu remains Enabled,
that is, the parameter Blocked is set to Yes and the parameter TestMode
under Main menu/Tests/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 Enabled, are reset when a new test
mode session is started.
Procedure
1. Click the Function test modes menu.
The Function test modes menu is located in the local HMI under Main menu/
Tests/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.
Apply input signals as needed according to the actual hardware and the
application configuration.
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/Tests/Function
status/Monitoring/CVMMXN/1:CVMMXN/Outputs. Then navigate to the
bottom of the list to find the frequency.
Check both analog primary and secondary values, because then
the CT and VT ratios entered into the IED are also checked.
