  • A measuring system to test current transformers at high frequencies for power quality analysis 
    Santos, Alejandro; López, Gonzalo Andres Aristoy; Trigo, Leonardo; Brehm, Marcelo; Slomovitz, Daniel (2015)
    The increase of distorted loads and non-conventional generation has led to limit the harmonic distortion in power networks. However, current instrument transformers (CT) are usually designed and tested only at power ...
  • Wideband resistive voltage divider for a standard wattmeter 
    Slomovitz, Daniel; Trigo, Leonardo; Lopez, Gonzalo Andres Aristoy; Brehm, Marcelo; Kyriazis, Gregory Amaral (2015)
    This work shows the state of development of resistive voltage dividers for use in a standard wattmeter that covers a frequency range from 50 Hz to 100 kHz. The voltage ranges go from 4 V to 1024 V, with required accuracy ...
