Figure 51: Connection example of the test equipment to the IED when test
equipment is connected to the transformer input module
13.2.5 Verifying analog primary and secondary measurement
Verify that the connections are correct and that measuring and scaling is 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 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/
Measurements/Monitoring/ServiceValues(MMXU)/SVRx. 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/Settings/General settings/Analog modules
