SUMMARY:Choosing the right VSD for tunnel ventilation application
DESCRIPTION:Overview\nIn recent years\, several tunnel projects have faced serious setbacks due to catastrophic motor failures. These failures are caused by high peak voltages\, a result of using Active Front End (AFE) VSDs combined with long motor cable lengths\, extending to 500 meters. This session examines the underlying electrical phenomena contributing to these issues and why conventional mitigation methods\, such as standard filters\, are often insufficient. \nParticipants will gain practical insight into proven engineering solutions that deliver near-sinusoidal voltage at the motor terminals\, reducing stress on insulation and extending asset life. Drawing on real-world case studies and field testing\, the session highlights key design considerations\, specification pitfalls\, and lessons learned to support more reliable tunnel ventilation system performance. \nLearning outcomes\nIn this event\, attendees will be able to: \n\nidentify the root causes of high peak voltages in AFE VSD tunnel applications\nevaluate why conventional filtering methods may not adequately protect motors apply practical design and specification strategies to prevent premature motor failure\nselect VSD and mitigation solutions that improve reliability and extend asset life\n\nProgram\nIn-person: \n\n5.00 pm AEST: Guest arrivals and registrations\n5.30 pm AEST: Presentation begins\n6.15 pm AEST: Q/A begins\n6.30 pm AEST: Event close\n\nOnline: \n\n5.30 pm AEST: Presentation begins\n6.30 pm AEST: Presentation ends\n\nAbout the speakers\n\n\n\nJoris Feekman\nRegional Sales Manager\, Danfoss Drives\n\nJoris is Regional Sales Manager at Danfoss Drives\, with over 25 years of experience in electrical drives and industrial power conversion.
