Title:
METHOD AND APPARATUS FOR PROTECTING POWER SYSTEMS FROM EXTRAORDINARY ELECTROMAGNETIC PULSES
Document Type and Number:
WIPO Patent Application WO/2010/047890
Kind Code:
A4
Abstract:
One form of the invention provides a method and apparatus for preventing an extraordinary electromagnetic pulse from reaching and rendering inoperative an electrical component of an electrical power system, wherein the component is located in a conductive path of the system that receives the pulse. The method and apparatus comprises the steps or means for detecting the presence of the pulse in the conductive path prior to the pulse reaching and rendering inoperative the electrical component. The pulse is diverted around the electrical component with a low inductance, high current capacity circuit relative to the electrical component before the pulse can reach and render the electrical component inoperative. The foregoing invention may beneficially utilize a high-speed current shunt comprising a flat conductive metal strap having a defined current-measuring region, a tapered parallel-plate transmission-line matching transformer attached to the current-measuring region and an output via a coaxial cable.
