  • High - voltage thin - layer fuses

    Publication

    - Year 2003

    Zaprezentowano nową technologię i konstrukcję bezpieczników wysokonapięciowych wykorzystując technologie stosowane w mikroelektronice. Cienką warstwę topika naniesiono na quasiceramiczne podłoże. Wykonane modele bezpieczników charakteryzują się wysoką pewnością działania oraz małymi stratami I2t.

  • Arc Ignition Process in Short Fuses Element

    Publication

    - Year 2003

    Przedstawiono wyniki badań zapłonu łuku elektrycznego w topiku w warunkach dużej stromości narastania gęstości prądu, do 5.19 9 A s-1 mm-2. Wyznaczono podziałkę rozpadu topika (0,04-0,12 mm) oraz napięcie zapłonu na elementarnej przerwie topika (20-30 V). Wykazano w badaniach doświadczalnych modelu fizycznego topika rozpad i ponowne łączenie sąsiednich elementarnych przerw.

  • The concept of a new two-stage fuse for high power pulse forming

    Publication

    This manuscript introduces the concept, physical operating principle and studies on a new and unique two stage forming fuse (TSFF) with interstage spark gap commutation and presents its application for forming high power pulses of extreme parameters. The paper classifies TSFF performance and compares it with conventional single-stage forming fuses. The conclusions are supported by analytical and experimental studies in laboratory...

  • Remarks on the Subject of Back-Up Protection of Residual Current Devices

    Publication

    - Year 2019

    Residual current devices without integral overcurrent protection (RCCBs) are back-up protected by fuses or miniature circuit-breakers (MCBs). If the latter are used, special attention must be given to the coordination between an RCCB and an MCB. This paper indicates probable cases of the aforementioned devices coordination, in which back-up protection of the RCCB is not adequate. A laboratory test has shown that depending on the...

  • A Multi-Antenna Scheme for Early Detection and Mitigation of Intermediate GNSS Spoofing

    Publication

    - SENSORS - Year 2019

    This article presents a method for detecting and mitigating intermediate GNSS spoofing. In this type of attack, at its early stage, a spoofer transmits counterfeit signals which have slight time offsets compared to true signals arriving from satellites. The anti-spoofing method proposed in this article fuses antenna array processing techniques with a multipath detection algorithm. The latter is necessary to separate highly correlated...
