In this paper, The architecture, communication implementation, technical characteristics, management systems and applications etc. of the online power quality monitoring system, which is based on transparent forwarding technique, are described. The system would have good application prospects for its strong compatibility, scalability, and efficiency.
This article presents a software developed for analysis of phenomena related to the power quality (PQ) in industrial systems, as variation of voltage, harmonic distortion and imbalance voltage, where the results are conveniently visualized in an user-friendly interface. This software intends to replace, in most situations, measurements made by traditional meters of PQ (equipment of high cost and rare...
IEC 61000 - 4-30 is an excellent standard that ensures that all compliant power quality instruments, regardless of manufacturer, will produce the same results when connected to the same signal. However, instruments that comply with the class A requirements of this standard have, until now, been too expensive for common use. Now a new set of technologies developed by an American company, in cooperation...
