Harmonic Mitigation Using Phase-shifting Transformers and Harmonic Filters
Published by Alex Roderick, EE Power – Technical Articles: Harmonic Mitigation Using Phase-shifting Transformers and Harmonic Filters, May 21, 2021. Learn about how minimise the presence of harmonics in an electrical system with harmonic transformers and filters. Three-phase loads do not generate triplen harmonics. Therefore, harmonic problems in situations where 3-phase loads dominate are primarily fromContinue reading “Harmonic Mitigation Using Phase-shifting Transformers and Harmonic Filters”
Developing Infrastructure to Charge Electric Vehicles
Published by U.S. Department of Energy – Energy Efficiency and Renewable Energy Alternative Fuels Data Center Consumers and fleets considering electric vehicles (EVs)—which include all-electric vehicles and plug-in hybrid electric vehicles (PHEVs)—need access to charging stations. For most drivers, this starts with charging at home or at fleet facilities. Charging stations at workplaces and public destinations may help bolster market acceptanceContinue reading “Developing Infrastructure to Charge Electric Vehicles”
