    • The effect of real network phase disturbances on the calculation of IEC 61000-4-30 parameters 

      Rens, Johan; De Kock, Jan; Van Wyk, Willie; Van Zyl, Jacobus (IEEE, 2014)
      Real life network dynamic phenomena are used to demonstrate how the calculation of IEC 61000-4-30 parameters can be affected. The voltage frequency can change instantaneously at a point in the network due to a shift in the ...
    • Where is the power of the IEEE 1459-2010 

      Rens, Johan; Van Rooyen, Tian; De Jager, Francois (IEEE, 2014)
      The integration of the IEEE 1459-2010 power definitions with the IEC 61000-4-30 PQ standard is investigated. A Class A PQ instrument, which record network coherent data with an absolute time uncertainty of less than 100 ...
