AB Power   quality    monitoring   is   assuming   anincreasing   importance   because   of   the   large   diffusion   ofnonlinear  and  time-varying  single-phase  and  three-phase  loadsand  their  interactions  with  the  power  supply  system.  This  hasmade that the industrial electrical consumer systematically usesmeasure  equipment  to  evaluate  the  electric  power  quality.  Themeasurements  show  that  the  harmonics  of  the  waveforms  arevariable  alongwith  the  time  due  to  the  changes  in  the  loadconditions and in the system  configuration. Thus, the electricalusers dispose of a great quantity of data from such of the threephases of the supply. Therefore, it is necessary to find a way tocharacterize   this   great   group   of   registered   data.   Thus,   theobjectives  of  this  work  are:  firstly,  to  propose  two  indices,  athree-phase  total  demand  distortion  index  and  a  three-phasetotal  unbalance  index;  secondly,  this  paper  proposes  a  simpleway  to  characterize  thegroups  of  data  in  an  statistical  waywhich  make  easy  its  representation.  The  study  carried  out  isapplied  to  the  data  recently  registered  in  an  electrical  powersystem.
