1. The detection current is differentFor loop resistance detection, the detection current should not be less than 100A, and the loop resistance or loop resistance can be directly measured at 100A, 200A, 300A, 400A, 500A or 600A.The measurement current of the DC resistance tester is generally: 1A, 3A

Why is the impact test done before the transformer is put into operation?
