These checks shall be repeated for Analog primary values.4. Inject an unsymmetrical three-phase voltage and current, to verify that phases arecorrectly connected.If some setting deviates, check the analog input settings underMain menu/Configuration/Analog modulesMeasured values such as current and voltages as well as active, reactive and apparentpower, power factor phase angles as well as positive and negative and zero sequencecurrents and voltages are available in the local HMI under Main menu/Tests/Functionstatus/Monitoring.Navigate to the measurement function that contains the quantity to be checked.Table 1:Measurement functionsFunction Quantity DescriptionCMMXU IA to IC amplitude, range and angleCMSQI 3I0; I1 and I2 amplitude, range and angleCVMMXN S; P; Q; PF; Ilag; Ilead; U; I and f amplitude, range and angleVMMXU VA_C to VC_A i.e. phase-to-phaseamplitude, range and angleVMSQI 3U0; U1 and U2 amplitude, range and angleVNMMXU VA to VC i.e. phase-to-neutral amplitude, range and angleAlso the Signal Monitoring tool in PCM600 can be used to read the measured values. Inmany cases it is more convenient to use PCM600 since, among many things, reports onmeasured values can be exported from the Signal Monitoring tool to other tools (forexample, MS Excel) for further analysis.5.7 Testing the protection functionalityEach protection function must be tested individually by secondary injection.• Verify operating levels (trip) and timers.• Verify alarm and blocking signals.• Use the disturbance handling tool in PCM600 to evaluate that the protection functionhas received the correct data and responded correctly (signaling and timing).• Use the event viewer tool in PCM600 to check that only expected events haveoccurred.1MRK 505 293-UUS A Section 5Testing IED operation43Commissioning manual
