• Estimation of the uncertainty of the AC/AC transducer output voltage

  Publikacja

  • A. Dzwonkowski
  • A. Golijanek-Jędrzejczyk

  - Przegląd Elektrotechniczny - Rok 2015

  The paper presents a methodology for estimating uncertainty of voltage transducers processing function, on the example of CYVS411D07 voltage transducers. The analysis was conducted using the method based on the GUM Guide propagation of uncertainty law and the determination of the coverage factor based on the effective number of degrees of freedom (t-Student distribution). The paper also presents example evaluation results of measured...

• Single and Three -Phase PWM AC/AC Converters as Semiconductor Transformers

  Publikacja

  • R. Strzelecki
  • N. Strzelecka

  - Rok 2020

  AC voltage transformation circuits contain pure or reactance PWM AC/AC converters. These circuits can be treated as AC/AC semiconductor transformers. This paper reviews single-phase and three-phase topologies: both non-isolated and isolated, single as well as two quadrant structure. Additionally, this paper present selected examples of their applications.

• Hybrid stepless distribution transformer with four-quadrant AC/DC/AC converter at low voltage side - simulation tests

  Publikacja

  • R. Strzelecki
  • W. Matelski
  • V. Tomasov

  - Przegląd Elektrotechniczny - Rok 2018

  The article presents the work of the stepless hybrid distribution transformer (HT), as an alternative to the so far applied Automatic Voltage Regulator (AVR) solutions, used to control the voltage in the power system in terms of the fundamental harmonic. The HT is a combination of a conventional distribution transformer and an AC/DC/AC converter connected in series with the transformers secondary winding. In the work the basic...

• AC Motor Voltage and Audible Noise Dataset

  Publikacja

  • B. Pałczyńska

  - Rok 2022

  The dataset titled AC motor voltage and audible noise waveforms in ship’s electrical drive systems with frequency converters contains the voltage and sound measurement results recorded in a marine frequency controlled AC drive system. The dataset is part of research focussing on the impact of the ship’s electrical drive systems with frequency converters on vibrations and the level of audible noise on ships. The dataset allows the...

• Hydraulic loss coefficients in 1D Flows

  Publikacja

  • J. Sawicki

  - Archives of Hydro-Engineering and Environmental Mechanics - Rok 2007

  Wyniki pomiarów pokazują, że współczynniki strat energii mechanicznej dla przepływów niejednostajnych i nieustalonych przyjmują wartości zdecydowanie większe, niż tradycyjnie przyjmowane dla ruchu jednostajnego. W pracy przedstawiono ananizę możliwych przypadków ruchu oraz wyniki obserwacji laboratoryjnych.Wykazano, że wzrost wartości współczynników jest uzasadniony fizykalnie.Zaproponowano robocza metodą ich korygowania.
