    • Impact of aggregation interval on harmonic phase angle measurements 

      Peterson, Brandon; Rens, Johan; Botha, Gerhard; Blanco, Ana Maria; Meyer, Jan (IEEE, 2018)
      The aggregation principles of IEC 61000-4-30 is a well-known concept implemented in Power Quality (PQ) recorders. Only rms data is retained. Harmonic emission assessment requires the analysis of harmonic phasors. Continuous ...

    • Measurement uncertainty of current harmonics during the assessment of compliance to grid code requirements 

      Maraiz, Zander; Rens, Johan; Peterson, Brandon; Botha, Gerhard (IEEE, 2018)
      This paper improves the impact of measurement uncertainty on harmonic grid code compliance assessment by characterization of the current transformers at a renewable power producer. Field data was collected to evaluate the ...

    • Network resonance detection using harmonic active power 

      Bottenberg, Agknaton; Peterson, Brandon; Rens, Johan; Debruyne, Colin; Knockaert, Jos (IEEE, 2018)
      Resonances in electrical distribution systems can result in amplification of harmonics, which is undesirable in electrical networks. To avoid intrusive measurement techniques, in the majority of the cases network modeling ...

    • On the remote calibration of voltage transformers: validation of opportunity 

      Rens, Sané; Rens, Johan; Holm, Johann; Botha, Gerhard; Desmet, Jan (IEEE, 2018)
      Remote calibration of instrument transformers seems possible if sufficient certainty in field measurements can be achieved. This opportunity, until now, was only investigated from a theoretical point of view and in this ...
