The Total Harmonic Distortion (THD) measurement is among the key elements to assess the power quality of a network. However, the Standards does not provide sufficient information to evaluate the uncertainty related to THD, neither voltage nor current one. Therefore, this work tackles the uncertainty estimation of the current THD measured by off-the-shelf inductive current transformers. The uncertainty computation is performed by a consolidated expression presented by the authors. Finally, the actual measurements of THD and the computation of its uncertainty are compared with those estimates with the presented expression.

Abstract
The Total Harmonic Distortion (THD) measurement is among the key elements to assess the power quality of a network. However, the Standards does not provide sufficient information to evaluate the uncertainty related to THD, neither voltage nor current one. Therefore, this work tackles the uncertainty estimation of the current THD measured by off-the-shelf inductive current transformers. The uncertainty computation is performed by a consolidated expression presented by the authors. Finally, the actual measurements of THD and the computation of its uncertainty are compared with those estimates with the presented expression.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
