The validation of single point measurements for the localization of multiple harmonic sources
Power quality management requires inexpensive and simple methods for electric power quality monitoring. This paper investigates the validity of single point measurements for the localization of sources of waveform distortion ...
On the development of a power quality benchmarking model
The development of a Power Quality (PQ) Benchmarking model is presented. Practical results are discussed to motivate the need of adding value to recorded PQ data by means of benchmarking PQ performance. The importance, ...
Evaluation of system losses due to harmonics in medium voltage distribution networks
Power system harmonics are a known cause to failure, disoperation or premature aging of customer's equipment. It also causes additional losses in a distribution network that influence the planning and design of future ...
Impact of aggregation interval on harmonic phase angle measurements
The aggregation principles of IEC 61000-4-30 is a well-known concept implemented in Power Quality (PQ) recorders. Only rms data is retained. Harmonic emission assessment requires the analysis of harmonic phasors. Continuous ...
