Test categories. Fig. 15 and Fig. 16 show the measured voltages during a three-phase and a two-phase voltage dip respectively. Fig. 15. Three-phase voltage dip Depth 100 Duration 510 ms. Fig. 16. Two-phase voltage dip Depth 50 Duration 150 ms. To guarantee the continuity of supply the wind turbine will be undergone to three consecutive tests. If the wind turbine disconnects during this test sequence four consecutive tests will be performed. If in this new sequence the wind turbine disconnects the test will be considered invalid. To verify wind systems by applying the Particular Verification Process the power and energy registered must fulfill the requirements shown in Table 4 and Table 5. Three phase faults OP requirements ZONE A Net consumption Q 15 Pn 20 ms . ZONE B Net consumption P 10 Pn 20 ms . Net consumption Q 5 Pn 20 ms . Average Ir Itot .
