  1. The coordination of transient protection for solid-state power conversion equipment

    https://www.nist.gov/system/files/documents/pml/div684/Coordination_1982.pdf
    The Coordination of Transient Protection for Solid-State Power Conversion Equipment François Martzloff Corporate Research and Development General Electric Company Schenectady, New York, USA f.martzloff@ieee.org © 1982 IEEE Reprinted, with permission, from Conference Record, 1982 IEEE/IAS International Semiconductor Power Converter Conference, May 1982. Significance Part 6 – Tutorials Part 8 – Coordination of Cascaded SPDs This paper was presented as a tutorial aimed at a semiconductor-oriented audience, giving an overview of the origin of transient overvoltages and of IEEE and IEC documents under consideration in the early eighties, identifying and categorizing transients. A brief review of available techniques and devices follows, with a description of the principles of coordinated protection, specific experimental examples, and results reconciling the unknown with the realities of equipment design.

  7. Revisiting reality checks on the surge environment

    https://www.nist.gov/system/files/documents/pml/div684/Revisiting.pdf
    AJWG-77B(Martzloff/Erlanaen)0l November 1995 International Electrotechnical Commission Technical Committee 77 - Electromagnetic Compatibility Subcommittee 778 - High-Frequency Phenomena Contribution to: Joint Working Group on Overvoltage Control From: Frangois D. Martzloff Revisiting reality checks on the surge environment In our quest for data on the frequency of occurrence and level of threat of overvoltages, we should not overlook some "reality checks" that can be applied to proposals for characterizing the surge environment. In the white paper (Martzloff/London)l of July 1995, four examples of reality checks were cited to inject some perspective in the process and avoid excessive conservatism in assessing the need for high current requirements for SPDs installed in buildings. Two of these raised questions from the AJWG, which I will attempt to clarify in this follow-up white Questions: ...
