|Rated Voltage||Work Voltage||AC Current|
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
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.
