Analysis on Some Problems in Current Injecting Test

At present,the current injecting test of TA circuit is the most effective and necessary check method.These tests can not only measure the impedance of secondary circuits,but also check the integrity of secondary circuits.Based on the analysis of two examples,this paper puts forward some problems to be paid attention in current injecting test,proposes the related measures,and supplies scientific insurance of correct current injecting test.
