|This issue features another outstanding contribution belonging to the “Education Corner” series. The first article is entitled “A Brief SPICE (Pspice) Tutorial” and is authored by Professor Clayton R. Paul, who presents a concise and practical summary of the most popular electric circuit analysis computer program. Professor Paul’s intent is to suggest the use of SPICE as a standard tool to study circuit-modelled EMC problems, as one uses the calculator to evaluate mathematical expressions. This paper is derived by a repeated presentation on the subject by Professor Paul at the Global EMC University, a presentation that always received the highest appreciation of the attendees. Readers with a limited SPICE familiarity may try to reproduce the various examples of this tutorial and acquire, through them, the necessary skills to comfortably use this tool for their future circuit simulations.
The second article is an interesting contribution on Supplement #1 of the Guide of Uncertainty in Measurements (GUM) and its application to EMC measurements, by Dr. Carlo F. M. Carobbi of Florence University in Italy. After having discussed the use of dBs to express electrical quantities commonly employed in practice and the statistics of dB-related uncertainties, Dr. Carobbi in this second paper points out the fundamental limitations of the GUM uncertainty approach, and discusses the conditions for application of the numerical procedure described by GUM Supplement #1. Operators of EMC tests, required to determine the uncertainty budget of their measurements, will undoubtedly benefit from this explanation of the GUM Supplement.
The third paper is entitled “Lightning-generated Fields in Reinforced Concrete Buildings” by Michel Mardiguian, a French EMC expert and consultant. This contribution describes the results of extensive studies, models and validation of the amplitudes of the residual fields inside a one-story building struck by lightning, for different locations of lightning impacts. The author points out that formulas for magnetic field attenuation found in the relevant IEC documents are questionable, under certain conditions.
In conclusion, I encourage (as always) all readers to actively participate to this column, either by submitting manuscripts they deem appropriate, or by nominating other authors having something exciting to share with the Community. I will follow up on all suggestions, and with the help of independent reviewers, I truly hope to be able to provide a great variety of enjoyable and instructive papers.
