  • Behavior of voltage transformers under distorted waveforms 
    Lopez, Gonzalo Andres Aristoy; Slomovitz, Daniel; Trigo, Leonardo; Santos, Alejandro; Brehm, Marcelo (2017)
    In this work, we present testing results of voltage transformers (VT) errors, under distorted waveforms. Different types of VT used in high voltage power networks were analyzed. This includes inductive as well as capacitive ...
  • Calibration system for voltage transformers under distorted waveforms 
    Lopez, Gonzalo Andres Aristoy; Slomovitz, Daniel; Santos, Alejandro; Trigo, Leonardo; Brehm, Marcelo (2017)
    In this work, we describe a programmable high-voltage source to test the behavior of voltage transformers under distorted waveforms at nominal voltages, as well as the measurement system for computing their errors at each ...
  • Intercomparación de capacidad en alta tensión entre INTI y UTE: resultados preliminares 
    Slomovitz, Daniel; Brehm, Marcelo; Izquierdo, Daniel; Faverio, Carlos; Casais, José Luis; Cazabat, Marcelo (2017)
    En este trabajo presentamos resultados preliminares de un estudio de intercomparación de capacitancia en alto voltaje. El patrón viajero fue un condensador, aislado en SF6, 400 kV, 50 pF. Este condensador se calibró en ...
  • Wideband resistive voltage dividers: progress report 
    Slomovitz, Daniel; Trigo, Leonardo; Lopez, Gonzalo Andres Aristoy; Brehm, Marcelo; Kyriazis, Gregory Amaral (2017)
    In this work, we describe the progress of the design of resistive voltage dividers for use in a standard wattmeter. It covers the frequency range from 50 Hz to 100 kHz and voltages from 4 V to 1024 V.
