At the same time, this value should be compared with the manufacturer's specified value, the change should not be greater than 5 %. If the MOA is too low, it may explode under the transient overvoltage of various operations and faults. If the surface of the MOA ceramic cover is seriously damped, the measurement value will also be affected, so the surface leakage should be eliminated during the test. Measurement of alternating current leakage of operating voltage. The test is to measure the total current, resistance current and power loss.
If the total current value is measured to be more than 20 % higher than the initial value, or to exceed the manufacturer's specified value, it should cause immediate concern and strengthen the operation monitoring. If the total current value is measured to be more than 50 % higher than the initial value, the operation should be eliminated.
If the measured resistance current more than double the factory's specified value, should also be out of operation, until the reason for removal or replacement, but can not take the fault operation. In conducting the above-mentioned tests on MOA, the current ambient temperature, relative humidity and operating voltage should be recorded, and the effects of the related interference should be noted and eliminated in the tests.
