Metal oxide varistor feasibility study
Abstract
We have successfully fabricated varistor material meeting the initial voltage stabilization specifications for the Dual Axis Radiographic Hydratest (DARHT) facility. A time dependent voltage droop ('overshoot') has been identified as a potential issue and some promising avenues to reduce the overshoot are outlined. In particular, preliminary tests using series capacitance gives an overshoot of a few percent. These data, coupled with our previous experience on low-overshoot varistor formulations, lead to the conclusion that specially tailored varistor material might be suitable for the DARHT application.
