Defining Interharmonics

White Paper, April 2013 Contributed by Chris Mullins, VP of Engineering and Operations, Power Monitors, Inc. Email: cmullins@powermonitors.comWebsite: http://www.powermonitors.comTel: 800.296.4120 ABSTRACT Interharmonics are frequency components at noninteger harmonics of the line frequency. The proliferation of large DC-converter variable speed drives and wind/solar inverter generation has led to an increase in interharmonic levels. Troubleshooting the resultingContinue reading “Defining Interharmonics”

Part 6: AC Power Distribution Systems & Standards (Power Quality)

Published by Nikola Zlatanov* Power Quality Terms Technical Overview Introduction Sensitive electronic loads deployed today by users require strict requirements for the quality of power delivered to loads. For electronic equipment, power disturbances are defined in terms of amplitude and duration by the electronic equipment operating envelope. Electronic loads may be damaged and disrupted, withContinue reading “Part 6: AC Power Distribution Systems & Standards (Power Quality)”
