Apply input signals as needed according to the actual hardware and
the application configuration made in PCM600.
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.
These checks shall be repeated for Analog primary values.
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
Measured values such as current and voltages as well as active, reactive and
apparent power, power factor phase angles as well as positive and negative and
zero sequence currents and voltages are available in the local HMI under
Main
menu/Tests/Function status/Monitoring
.
Navigate to the measurement function that contains the quantity to be checked.
