VⅡ Defense tests
The product should do defense tests before running or each two years during operation,Items and ways are as following:
1.Reference voltage at 1mA D.C: D.C.voltage which applied on the terminals of MOA is tested after the current through MOA stable at 1mA.The value should be in accordance with the requirement listed in the table of technical parameters.
2.Leakage current tests:reference voltage at 0.75U1Ma D.C.which applied on the terminals of MOA,the current passed MOA≤50μA.
3.Avoid to do the power frequency spark over voltage tests.
VⅢ Notes
1.The product shall be stored in the warehouse with temperature±40℃,acid &alkali free or other harmful impurities.
2.To avoid MOA umbrella skirt stressed.
3.To avoid scratch the umbrella skirt by sharp instrument in installation.
4.In MOA installation,if there is welding work around,it should be to protect MOA from fire.
5. In MOA installation, avoid twisting the terminals of MOA, especially pay much attention when the terminals of MOA and primary busbar not in a line.
