Measurement results used for Power Quality assessment give an objective evaluation if their trust level is high. This requirement becomes feasible if a system for ensuring measurement quality is already in place and it is adapted to measurements specific domain. The system for ensuring measurement quality is absolutely necessary when measurement results are used to take correct decisions. Because...
The determination of power quality levels, through objective approach, is based on recordings of measurement information. For a more complete characterization of power quality parameters, the measurement process is required to include measurements of the alternating current as well, as specified in IEC 61000–4 series regulations "Electromagnetic Compatibility". In this article we present...
The purpose of Power Quality measurements can be either continuous “surveillance” as a task performed by the Distribution System Operator or specific parameter “evaluation” for limit violation. Individual strategies can be applied for each goal but a combined approach is preferred. This paper presents a comparison between results obtained using an electricity meter with Power Quality capabilities...
The knowledge power quality levels, through objective approach, is based on the accumulation as measurement information. For a more complete characterization of power quality parameters it is necessary that the measurement process to include in the set of specific operations and evaluation of measurement uncertainty. Measurement uncertainty is a specific parameter of measurement method and conditions...
