Section 4 Testing IED operation4.1 Preparing the IED to verify settings• If a test switch is included, start preparation by making the necessary connectionsto the test switch. This means connecting the test equipment according to aspecific and designated IED terminal diagram.• Put the IED into the test mode to facilitate the test of individual functions andprevent unwanted operation caused by other functions. The test switch shouldthen be connected to the IED.• Verify that analog input signals from the analog input module are measured andrecorded correctly by injecting currents and voltages required by the specificIED.• To make testing even more effective, use PCM600. PCM600 includes the Signalmonitoring tool, which is useful in reading the individual currents and voltages,their amplitudes and phase angles. In addition, PCM600 contains the Disturbancehandling tool. The content of reports generated by the Disturbance handling toolcan be configured which makes the work more efficient. For example, the toolmay be configured to only show time tagged events and to exclude analoginformation and so on.• Check the disturbance report settings to ensure that the indications are correct.• For test functions and test and signal parameter names, see the technical manual.The correct initiation of the disturbance recorder is made on start and/or releaseor trip from a function. Also check that the wanted recordings of analogue (realand calculated) and binary signals are achieved.Parameters can be entered into different setting groups. Makesure to test functions for the same parameter setting group. Ifneeded, repeat the tests for all different setting groups used. Thedifference between testing the first parameter setting group andthe remaining is that there is no need for testing the connections.• During testing, observe that the right testing method, that corresponds to theactual parameters set in the activated parameter setting group, is used.• Set and configure the functions before testing.Most functions are highly flexible and permit a choice of functional and trippingmodes. The various modes are checked at the factory as part of the designverification. In certain cases, only modes with a high probability of coming intooperation need to be checked when commissioned to verify the configuration andsettings.Requirements for testing the function.1MRS756801 E Section 4Testing IED operation630 series 23Commissioning Manual
