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. He has experience across Europe and Australia\, delivering reliable motor control solutions across a wide range of industrial applications.\n\n\n\n\n\n\n\n\nHusain Natalwala\nBusiness Development Manager\, Danfoss Drives\nHusain has strong experience supporting large-scale industrial and infrastructure projects\, with exposure to Industrial Automation and Electrical Systems. At Danfoss\, he works as a BDM focussing on Tunnel Ventilation\, Water and Food Industries.

SUMMARY:Conversations that connect: mentors & mentees
DESCRIPTION:Overview\nTransform the way you connect with your mentor or mentee. This interactive hybrid workshop (featuring innovative ‘watch parties’ in Sydney\, Melbourne and Brisbane) focuses on moving beyond surface-level networking to purposeful\, engaging conversations that build lasting value. It is being delivered by the ATS Diversity Group’s cutting edge Mentor Alliance Program. \nParticipants will learn how to design effective discussion frameworks\, apply practical networking strategies\, and co-create ideas for future mentor–mentee catch-ups. Led by an online expert and supported by local facilitators in Melbourne\, Sydney\, and Brisbane\, the session features hands-on activities that spark meaningful\, structured dialogue. \nJoin fellow mentors and mentees in your local hub to deepen connections\, strengthen your mentoring relationships\, and help shape how the Mentor Alliance connects in the future. \nWhile it is a Mentor Alliance event\, it is open to everyone within ATS. \nNOTE – This exciting event is intended to be delivered by Patricia online to ‘watch parties’ in Melbourne\, Sydney and Brisbane’s EA offices\, so people can connect and use these as “breakout rooms.” We urge you to attend one of these watch parties in person as you’ll get more out of the experience that way.  \nLearning outcomes\nIn this presentation\, you will learn: \n\nFramework Design: Learn how to select and structure discussion starters that move beyond small talk to deep engagement\nApply Networking Strategies: Practice hands-on techniques for sparking meaningful\, structured dialogue within the Mentor Alliance community\nFuture Collaboration: Be part of creating ideas for future catch ups between you and your mentor/mentee.\n\nProgram\nIn-person: \n\n5.30 pm AEST: Registrations open\n6.00 pm AEST: Presentation begins\n6.45 pm AEST: Q&A session\n7.00 pm AEST: Presentation ends\n7.30 pm AEST: Event ends\n\nOnline: \n\n6.00 pm AEST: Webinar begins\n6.45 pm AEST: Q&A session\n7.00 pm AEST: Webinar ends\n\n\n\n\n\n\n\n\n\n\n\nSpeaker\n\n\nUnfortunately\, Patricia Kaziro (who was originally scheduled to lead the session) is unwell\, but we’re pleased to share that our ATS QLD Chair\, Annalena Chapman\, will now be stepping in to lead both the presentation and the event. This will be a valuable and insightful discussion under Annalena’s guidance\, and we strongly encourage attending in person with us.
