The current level shall be selected based on the energy capability of the SPD as determined in the impulse durability test (see 6.2.1.6). Both impulse-limiting voltage and impulse dura- bility tests shall be performed with the same impul
34、se. Additional tests may be performed using waveforms selected from Categories Al, B, C and D as well as those listed in the SPD documentation. However, these tests are op- tional and should only be used as appropriate to the application of the SPDs. The cur- rent level shall be selected based on th
35、e energy capability of the SPD as indicated by the manufacturer. Unless otheiwise specified, apply five negative and five positive impulses for each impulse test. The generator used shall have its open-circuit voltage and short-circuit current selected from table 3. Measure the voltage limiting for
36、each impulse without load. The maximum voltage measured at the appropriate terminals shall not exceed the specified voltage protection level U,. Sufficient time shall be allowed between impulses to prevent accumulation of heat. It is understood that different SPDs will have different thermal charact
37、eristics, and consequently will require different times between impulses. If it is required, the impulse may be applied to terminals Xl-XZ of SPDs shown in figures lc) and le). For tests on the SPDs shown in figures lc) and le), each pair of terminals (Xi-C and XZ-C) may be tested at the same time a

For SPDs that have a common shunt element (refer to 4.3), the voltage on the line terminals which do not have the impulse applied shall be measured and it shall not exceed U,.
