According to military standards, passive electromagnetic LC filters of HEMP are recommended for use in all kinds of special-purpose electronic equipment. Experience gained by military specialists is usually employed when developing HEMP protection means and measures for civil equipment. Does it make sense to use extremely expensive and bulky HEMP filters for civil equipment? … [Read more...]
Electromagnetic Pulse: The Myths and Reality
Introduction Some 10-15 years ago this topic was irrelevant for the civil sector, and the issue of protection of electrical and electronic equipment from high altitude electromagnetic pulse (HEMP) solely belonged to military specialists. Today, much of the mass media discusses HEMP danger for civil infrastructure at the global level in all possible ways; and thus, this topic … [Read more...]
Preventing Impact of High-Altitude Electromagnetic Pulse on 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 … [Read more...]
HEMP Protection Strategy for Power System’s Electronic Equipment
Annotation The issue of protecting electronic equipment from the electromagnetic pulse of a high-altitude nuclear explosion is very relevant and important for the power industry. Current knowledge about individual HEMP protection elements, their specifications and application features is very important, but, at the same time, limited to ensure efficient protection of power … [Read more...]
Is Electric Equipment Grounding the Basic Protection Means Against HEMP?
Abstract The article discusses the differences between the electromagnetic pulses at lightning (LEMP) and at high altitude nuclear explosion (NEMP or HEMP). The article also shows that these differences do not allow to transfer LEMP experience on to NEMP. The author questions the effectiveness of grounding of electronic equipment as the main protection principle against … [Read more...]
