  • S. Galla

  - Rok 2005

  Przedstawiono metodę obniżenia poziomu intensywności zakłóceń w budynkach pracującego zakładu przemysłowego. Potrzeba wykonania badań pola elektromagnetycznego wynikała m.in. z zaobserwowanej wśród pracowników jednego z działów zakładu większej podatności na zachorowania. Na drodze pomiarów zlokalizowano źródła silnego pola magnetycznego w zakresie małych częstotliwości. Na podstawie analizy wyników pomiarowych sformułowano wnioski...

  • B. Kostek

  - Archives of Acoustics - Rok 2016

  The aim of this paper is two-fold. First, some basic notions on acoustic field intensity and its measurement are shortly recalled. Then, the equipment and the measurement procedure used in the sound intensity in the performed research study are described. The second goal is to present details of the design of the engineered 3D intensity probe, as well as the algorithms developed and applied for that purpose. Results of the intensity...

• Multidipoles model of ship's magnetic field

  Publikacja

  • M. Wołoszyn
  • P. Zimny
  • K. Jakubiuk

  - INTERNATIONAL JOURNAL OF APPLIED ELECTROMAGNETICS AND MECHANICS - Rok 2012

  Ships made of ferromagnetic metals interfere with Earth's magnetic field in their surrounding. The disturbance of the magnetic field makes possible localization and even identification of the ship, which could determine a threat to the ship. The measurement of the magnetic field around the ship enables to determine its magnetic signature. The paper presents a multidipoles model of the ship magnetic field, which allows to determine...

  - Rok 2007

  The 3-axis fluxgate magnetometer requires conducting a precise calibration in the magnetic field whose value is determined and which is characterized by the high uniformity of the distribution of the field, especially along the axis of the sensors. The generation of the magnetostatic field characterized by the high uniformity, can be achieved by using the Helmholtz's coils. The requirements of the uniformity of distribution of...

  - Rok 2005

  Do wymuszenia przerzutu prądu z bezpiecznika krótkotopikowego o dużym prądzie znamionowym, lecz małej zdolności wyłączania do do innego - o małym prądzie znamionowym, lecz dużej zdolności wyłączania konieczne jest wytworzenie przez bezpiecznik krótkotopikowy wysokiego napięcia łukowego. Do tego celu bezpiecznik z topikiem o długości 1 mm wyposażono w rożki łukowe i płykową komorę dejonizacyjną oraz zastosowano zewnętrzne pole...

• Development of the sound field 3D intensity probe based on miniature microphones

  Publikacja

  • J. Kotus
  • W. Moskwa
  • A. Czyżewski
  • B. Kostek

  - Rok 2015

  The engineered measuring probe uses three pairs of miniature microphones coupled. The signals from the microphones after an initial amplification are fed to differential circuits. Due to the required symmetry of the circuit it was necessary to select electronic components very carefully. Moreover, additional digital signal processing techniques were applied to avoid amplitude and phase mismatch. The view of the engineered probe...

• Research of leakage magnetic field in deenergized transformer

  Publikacja

  • J. Horiszny

  - COMPEL-THE INTERNATIONAL JOURNAL FOR COMPUTATION AND MATHEMATICS IN ELECTRICAL AND ELECTRONIC ENGINEERING - Rok 2018

  The article deals with the issue of the numerical analysis of the magnetic field occurring around the transformer after it has been powered down. The main goal of this analysis was to examine if it is possible to identify the residual fluxes in the transformer legs based on this fields’ measurements. It was also intended to determine the type and the location of magnetic sensors. Numerical analysis of the magnetic field was performed....
