Abstract [en]

It is argued that it is the intent behind the electromagnetic interference in intentional electromagnetic interference (IEMI) that causes problems to large distributed systems and facilities even if   they are designed by traditional zoning concept rules. Hardening such   facilities against IEMI requires a correspondence between the electromagnetic zone boundary and the physical access control boundary. The three characteristics of a facility, the accessibility, susceptibility, and consequence, are discussed in the context of vulnerability to IEMI. A methodology for classification of facilities

Abstract [en]

It has been shown earlier 121 that Ultra Wide Band (UWB) transients can travel in differential mode (DM) along low voltage power installation cables, and deliver large amounts of power to connected equipments. However, branches in the network were not included at that time. In this paper, the ability of UWB transients to propagate through different types of junctions of low voltage power cables is investigated. The received voltage could with very good accuracy be estimated from Transmission Line Theory, either using theoretical calculations or numerical simulations. This was verified experimentally. The decrease in voltage received at the loads of the branches is mainly due to the reflection caused by impedance mismatch at the junction. It is concluded that large voltages can be delivered to unprotected loads, if a UWB transient is injected in DM at another part of the same network.

Abstract [en]

In this paper, the propagation of ultra-wideband (UWB) transients through different types of junctions of low-voltage power cables and one real power network of a building were investigated. For the laboratory test, it was seen that the main mode of propagation in the cables and through the junctions tested is transverse electromagnetic (TEM). The received voltage could thus be, within a small error, estimated from transmission-line theory. The main cause for decreased voltage received at the loads of the branches of the junctions is reflections due to impedance mismatch of the junctions. Large voltages can be delivered to many unprotected loads connected to the junctions. UWB transients were also injected into a residential house using a power outlet available on the outside wall of the house. It was seen that the complexity of this network creates deviation from the TEM mode. However, relatively large voltages were still received at the various outlets inside the house. It is recommended that power outlets or lamp sockets outside buildings are controlled from inside using two-pole switches that reduce the received voltage to reduce the risk of conducted intentional electromagnetic interference.

Abstract [en]

A research program is being conducted at Uppsala University, Sweden, to investigate the possible susceptibility of civilian systems and networks to intentional electromagnetic interference (IEMI), with emphasis on the Swedish railway network. This paper reviews the details of the research program and some of the results.

Abstract [en]

Civilian handheld global positioning system receivers were tested for their susceptibility against radiated electromagnetic disturbances of different characteristics and field levels. This susceptibility data were compared to the existing electromagnetic compatibility (EMC) immunity requirements for electronic devices. Some of the receivers were disrupted by continues waves at in-as well as out-of-band frequencies, at field levels far below the existing EMC requirements. The possible reason for this is discussed. In general, due to the ever-growing use of commercial-off-the-shelf equipment even for critical functions, certificates of conformity to current EMC requirements may be inadequate.
