This paper looks at the harmonic indices and gives considerations about their random behavior. The indices taken into account refer to both the single customer point-ofcommon coupling and the entire electrical distribution system. The analysis of on-site measurements and numerical simulations on medium voltage distribution systems allow us to evidence that the peak factor is a valuable index to be included in a harmonic standard or in a power quality contract. Several system indices are proposed as useful metrics to qualify distribution systems able to take into account different quality service aspects. Generally, the selection of the most adequate one depends on the aspects judged more relevant.

Abstract
This paper looks at the harmonic indices and gives considerations about their random behavior. The indices taken into account refer to both the single customer point-ofcommon coupling and the entire electrical distribution system. The analysis of on-site measurements and numerical simulations on medium voltage distribution systems allow us to evidence that the peak factor is a valuable index to be included in a harmonic standard or in a power quality contract. Several system indices are proposed as useful metrics to qualify distribution systems able to take into account different quality service aspects. Generally, the selection of the most adequate one depends on the aspects judged more relevant.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
