stable operation. For two failed elements (Fig. 5), the voltage signal still has a very low signal-to-noise ratio with about a 2 V noise signal before and after the fault, with a differential voltage of just under 5 V after the element failure. However, it can be reasonably seen that the voltage goes up along with the current.
