  • 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 ...
  • Trilateral South American project: a reference system for measuring electric power up to 100 kHz – progress report II 
    Kyriazis, Gregory Amaral; Di Lillo, Lucas; Slomovitz, Daniel; Iuzzolino, Ricardo; Yasuda, Eliana; Trigo, Leonardo; Souza, Regiane Maria de; Laiz, Hector; Debatin, Rosane Moreira; Afonso, Edson (2017)
    Three countries in South America are jointly developing a reference system for measuring electric power up to 100 kHz. The objective is the construction of three similar measuring systems, one for each institute. The ...
  • Voltage-ratio calibration system up to 50 kHz 
    Trigo, Leonardo; Slomovitz, Daniel; Kyriazis, Gregory Amaral (2017)
    This paper describes a voltage-ratio measuring system up to 50 kHz. It is based on two Keysight 3458A digital multimeters, working in DCV sampling mode. An external trigger based on a rubidium clock, drives both digital ...
  • 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.
