Action load test When the maximum continuous working voltage Uc is applied, the gbaradi olugbeja shall be able to withstand the specified discharge current without unacceptable changes in its characteristics. In addition, the voltage switch-type gbaradi olugbeja or combined gbaradi olugbeja shall at least be able to cut off the freewheeling current of the dry rated short-circuit current I_SCCR.
