Ultrasound Diagnosis of Transformers and Motor Bearings

Drew Walts | Training Manager and ISO Training Coordinator, IRISS

Webinar Description

This webinar will go over two case studies from a food manufacture in the Midwest. Their CBM Analyst is Certified CAT 2 in ASU and IRT. He has partnered with the IRISS Technical Service Team to investigate fault conditions and help to expand the theory of Ultrasound Diagnostic and Sound Pattern Analysis. This CBM Analyst is the IRT Analyst as well and his use of both these technologies has been aided by outside service providers who perform the Vibration and Oil Analysis onsite. We will look at two unique case studies that used ultrasound and IR Cameras as their front-line testing technology and dive into a motor fault determination and fault detection of an oil filled transformer.

Learning Takeaways

  1. Benefits of the use of ultrasound devices.
  2. How Time Series and Frequency Spectrum Domains can find the fault conditions harmonics of occurrence
  3. How Oil Analysis can assist in determining the assets life cycle
  4. How Vibration plays a role in the determination of a fault condition of a motor

About the Presenter

Drew’s fascination with Infrared began in 1981 when  National Geographic Magazine released their Special Edition titled Energy which  featured a full front and back cover done with an infrared camera in what we call the Ironbow setting. He would go on to enlist in the U.S. Army where he served in Desert Storm as a Forward Observer which he got to use an Infrared Targeting system to spot targets for artillery strikes. He would later go onto being involved in the Fire Service where he became a Lieutenant in a volunteer fire department with 9 years’ service as well as operating with the NY State Region 4 HAZ-MAT Team as a Specialist out of Saratoga County NY. He also worked for a UE Systems for over 13 years traveling the world as a senior instructor and consultant where he would teach the use of Ultrasound & Infrared into an RCM/P/DM program.

His love of these technologies has led him to Author the most comprehensive book on Airborne/ Structure borne Ultrasound (ASU) and developed the ISO 18436 Part 8 ASU Certification CAT 1 -CAT 3 courses. He would go on to Co-Author and design the ISO 18436 Part IRT Certification CAT 1 -CAT 3 course materials which have been well received around the World for advancing beyond any previous versions of courses offered on the Theory of Infrared or Ultrasound. Drew Currently holds a CAT III IRT Certificate and CAT II ASU from IRISS. Previous he had been certified through TEGG as an ASNT SNT-TC-1a Level 1 Thermographer, Level 2 ASU through UE Systems and recently received a CAT I ASU from Mobius just to see the differences in materials between the 3 companies.

About the Author

Drew Walts Training Manager and ISO Training Coordinator, IRISS

Drew joined IRISS in June 2017.  He is an ISO CAT 2 Airborne/Structure Borne Certified Inspector and certified in Principles of Infrared. His responsibilities include developing IRISS’s Ultrasound & Infrared CAT 1 & 2 Certification Training courses in accordance with ISO 18436, part 7 & 8 and the CAT 1 ASU course was recently approved and adopted by Mobius.

Drew has assisted in the development of a Quality Assurance program for calibration and testing of ultrasound devices sold by IRISS.  He oversees a cross-functional repair team to insure rapid repairs of ultrasound devices from our clients.

Drew provides customer training for the Level 1 & 2 Infrared (IR) Certification courses and for the Windows Installer Certification course. He is working on insuring both sets of IR course material will pass the BiNDT audit process so IRISS can ultimately offer ISO 18436, part 7, IR classes and eventually, part 8 certification courses at the IRISS US and UK SMART Training Centers.

Drew is a Desert Storm veteran whose first exposure with IR was in the US Army where it was used to spot targets to call for artillery strikes. He quickly became fascinated with its use after his time in the military.

Drew is a former lieutenant at a volunteer fire department with 9 years’ service as well as a New York State HAZ-MAT Specialist with Saratoga County & NY State Region 4 HAZ-MAT Team. He was certified through L.E.T.A. (Law Enforcement Thermographers Association) and was responsible for teaching this exciting technology to the members of my department.

Drew worked for an ultrasound manufacturer for over 13 years traveling the world teaching the use of Ultrasound in a CBM, RCM & P/DM programs. Drew is passionate about this technology and how much it compliments IR, MCA and Vibration.
