The Critical Role of Power Quality Evaluation in Solar Installations

Published by Dranetz Technologies, Inc., Application Note EXECUTIVE SUMMARY As solar photovoltaic (PV) systems become more prevalent in commercial and industrial environments, the emphasis on financial return and concise performance expectations has rightly intensified. However, one often-overlooked aspect of solar deployment is the comprehensive evaluation of power quality (PQ)—both before and after installation. By identifying existing gridContinue reading “The Critical Role of Power Quality Evaluation in Solar Installations”

On the Processing of Harmonics and Interharmonics: Using Hanning Window in Standard Framework

Published by A. Testa member IEEE, D. Gallo student member IEEE, R. Langella member IEEE Abstract: The harmonic and interharmonic analysis recommendations contained in the latest IEC standards on Power Quality are considered. The spectral leakage problems, due to synchronization errors of the analysed waveforms with the window widths adopted are analysed. Improvements of theContinue reading “On the Processing of Harmonics and Interharmonics: Using Hanning Window in Standard Framework”

Safety Standards for Testing Instruments

Published by Alex Roderick, EE Power – Technical Articles: Safety Standards for Testing Instruments, November 24, 2021. IEC standards reduce safety hazards that can occur from unpredictable circumstances when using electrical test equipment such as test instruments and meters. The International Electrotechnical Commission (IEC) is an organization that develops international safety standards for electrical equipment. TheContinue reading “Safety Standards for Testing Instruments”

EMC for 2 to 150 kHz: A Proposal for Emission and Immunity of Equipment including Power-Line Communication

Published by Anders Larsson and Math Bollen, ELFORSK, Elforsk rapport 09:29, October 2008 Summary The frequency range from 2 to 150 kHz is not sufficiently covered in international standards. The contrast with the frequency range below 2 kHz is striking. There have traditionally been good reasons to emphasize on the lower frequency range, where theContinue reading “EMC for 2 to 150 kHz: A Proposal for Emission and Immunity of Equipment including Power-Line Communication”
