Commissioning manual
Any function is blocked if the corresponding setting in the local HMI
under Main menu/Test/Function test modes menu remains Enabled,
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 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/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 61850-9-2-LE
process bus, analog values from the transformer input module can be verified as follows.
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/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.
