HMUSA 2022 Conference: VFD Cables – Essential or Overkill

About the presentation
This presentation answers the questions:

• What is a variable frequency drive (VFD) cable and why do VFD cable constructions differ so much?
• Why do high-frequency pulse width modulation (PWM) waveforms create problems that don’t exist with 60Hz?
• What is radiated electromagnetic interference (EMI) and how can VFD cable reduce it?
• What is electromagnetic coupling and how can VFD cable reduce it?
• Why is common mode current a problem?
• How can VFD cables reduce undesirable effects of common mode current?

It also addresses:

• The importance of proper shield termination
• The dangers of using THHN cables between an inverter and motor
• Reflected Waves and Corona Inception Voltage
• The NFPA 79 and what it says about drive cable
• 600V, 1000V, and 2000V rated cable, what you need
• Cost differences between VFD cable and standard cable
• Various VFD cable constructions on the market

Meet your presenter

Steve Wetzel has an electrical engineering degree from the University of Wisconsin – Madison and is a principal engineer for The Southwire Company. He’s a member of the Insulated Cable Engineers Association (ICEA) and is active in the group responsible for creating a variable frequency drive (VFD) cable standard. Wetzel started learning about VFD systems and cables when he worked for Siemens and has been involved in VFD systems from the cable perspective ever since. He presents at training sessions and drive industry events each year on the role of the cable in drive systems. He works closely with Rockwell, ABB, Siemens, and Eaton application engineers regarding the role of the cable running between the drive and the motor. Wetzel is the author of numerous application notes on various aspects of the inverter to motor cables. In addition to VFD cables, he’s Southwire’s technical expert on other specialty cables, including factory automation, crane, mining, transit, and wind tower cables. In addition to working with ICEA, he’s also active on various Canadian Standards Association (CSA) technical committees for cable types. In his spare time, Steve pursues woodworking, photography, and fishing.
