Experimental Study on the Current Loss of MITL With Cathode Made of Different Stainless Steel.

Magnetically insulated transmission lines (MITLs) are key components in present high-power generators. In our experiments, the current density flows in the cathode of the MITL are so high that current loss cannot be neglected. At an input current of 0.7–1.4 MA, an experimental study on current loss is performed with austenitic and martensitic stainless steel. An empirical relation between loss current density and input current density was found. For current density around 1 MA/cm, the results show that the loss current density is nearly a power function of the input current density, and the power indices for austenitic and martensite stainless steel are about 4.3 and 3.3, respectively.
