High altitude electromagnetic pulse: Power transformers also need to be protected

Vladimir I. Gurevich

Sažetak

This article addresses the issue of geomagnetically induced currents (GIC) produced by electromagnetic pulse at a high-altitude nuclear explosion (HEMP) and its influence on power transformers. The article contains a description of the set of devices developed by the author that consists of a reliable electronic protective relay and a portable tester for its periodical testing, which are meant to resolve the problem. These devices, based on a standard electronic component, are suitable for mass production and can be widely used in power grids.
