Subject the IED to healthy normal load conditions for at least two seconds.2. Apply the fault condition and slowly decrease the measured impedance to findthe operating value of the phase-to-phase fault for zone 1 according to test point 1in figure 42 and table 19. Compare the result of the measurement with the setvalue.3. Repeat steps 1 to 2 to find the operating value for test points 2, 3 in table 19Observe that the zones that are not tested have to be blocked and the zone that istested has to be released.4. Repeat steps 1 to 3 to find the operating value for the phase-to-ground fault C-Gaccording to figure 43 and table 20.Test points 8, 9, 10 and 11 are intended to test the directional linesof impedance protection. Since directionality is a commonfunction for all six measuring zones, it is only necessary to test 8,9, 10 and 11 once, in the forward direction in order to test theaccuracy of directionality (directional angles). Directionalfunctionality testing (trip inside, no-trip outside) should always beSection 13 1MRK 502 073-UUS ATesting functionality by secondary injection150 Generator protection REG670 2.2 ANSI and Injection equipment REX060, REX061, REX062Commissioning manual
