Abstract: Because of the different test site and test load,AFDD often fails to accurately identify every fault arc or false release which leads to the failure of the test.In view of this situation,this paper discussed the test method about series arc fault test,parallel arc fault test and inhibitive load shielding test for AFDD,to provide some reference for detection mechanism and production enterprises.
