High Energy Surge Arrester Technology Development. Part 2.
Abstract
The objective of this program was the development of improved high energy surge arresters (HESAs) to protect installations from EMP induced on extended networks. This phase is associated with the development of a HESA for an RF/C3 transmitter antenna. A unique and innovative all solid state, self recovery HESA design concept was developed using existing metal oxide varistor and saturable magnetic device technologies. This design concept, which is based on a two element hybrid protective device approach, has the dual capability to provide high voltage/fast rise time and long pulse/high current threat protection. The first element provides delay free protection against the fast risetime HEMP threat and was implemented using our metal oxide power varistor product line technology which General Electric developed. The second element provides the high energy relief for the first element, and was implemented using saturable magnetics. Detailed analytical design equations were derived and extensive material characteristics were experimentally obtained in support of this development. Much of this work involved the generation of singular information which was required to support the solutions to the design problems encountered in meeting the design challenge using realistic hardware. Two proof of principle prototype units were designed and fabricated using the technology established in the program.
