In this paper, the possibility of extending the validity range of the transmission line theory in evaluating differential mode signals along two-wire lines above a ground plane is discussed through analysis and simulation. It is shown that, when the above-ground height of the two wires is larger than about twice their separating distance, the calculation of the characteristic impedance of the line...
Time-domain intentional electromagnetic interference (IEMI) signals can be very fast, making it difficult and costly for any detection, location or identification system to digitize them with full time and amplitude resolutions. This paper presents a novel technique for the identification of the type of waveform associated with an IEMI attack and for the estimation of the waveform parameters based...
The paper focuses on the extension to series-compensated multiconductor transmission lines of a new fault location method based on the Electromagnetic Time Reversal (EMTR) theory. The applicability of the EMTR theory to locate faults is first summarized. Then, the paper describes the proposed algorithm to locate faults in multiconductor transmission lines using a single observation point at one of...
We present in this paper an overview of conducted and radiated sources that could be considered as potential intentional electromagnetic interference (IEMI) sources against critical infrastructures associated with power systems. The sources are classified according to the commonly addressed criteria in IEMI. In addition, to assess their potential risk, reported IEMI sources are classified according...
The paper presents a new method based on the Electromagnetic Time-Reversal (EMTR) for locating faults in power systems. The applicability of the EMTR to electromagnetic transients associated with traveling waves in transmission lines originated by the fault is theoretically demonstrated. A new fault location technique is then proposed and illustrated for a simple case of a single-conductor transmission...
