First, check whether the appearance is intact.
Before the product is put into operation, measure the DC reference voltage U1mA, which shall not be less than the value specified in GB11032 - 2000. Measure the leakage current at 0.75 U1mA, and its value shall not be greater than 50μA. Measure it once every four years after commissioning to see if it meets the requirements. Gapless arresters are not allowed to undergo power - frequency discharge voltage tests.
