Preventing Impact of Geomagnetically Induced Current at High Altitude Nuclear Explosion on High-Power Transformers
Protection of a power system’s electrical equipment from a high-altitude (more than 30 km) nuclear explosion (HEMP) impact is a challenging issue, which until recently has not received proper attention. The fact is that HEMP does not affect people directly, while the electromagnetic pulse resulting from this explosion is a powerful devastating factor for the power grid’s electronic and power supply equipment. Since the electrical power industry is the foundation of any country’s infrastructure, such a feature of HEMP is very attractive for the military.
