2021 International Conference of Doble Clients: Panel Spotlight
As we kick off the 88th International Conference of Doble Clients, we wanted to share a few sessions you won’t want to miss. These interactive panel sessions offer different perspectives on important topics and give you the opportunity to learn from industry experts. From a deep dive into test techniques for underground cables, to the challenges of managing windfarm generator step up (GSU) transformers.
Commissioning and Maintenance Tests Techniques for Underground Cables
April 12, 12:45 p.m. – 3:00 p.m.
Many organizations may not have a great deal of experience with underground cables, and as a consequence, are often unsure of best practices for commissioning and maintenance of these assets. This panel includes end users and original equipment manufacturers to provide a well-rounded perspective on testing methods and best practices.
This educational session will walk participants through the various types of cable insulations as well as how to identify different types of deterioration — thermal, electrical, chemical — in cables. A detailed discussion of the pros and cons of power frequency, very low frequency, Tan Delta and
partial discharge testing will help participants understand the diagnostic value of each test. Case studies of actual testing illustrate typical test results and interpretation of the data.

Insurance Companies’ Perspectives and Issues
April 12, 3:30 p.m. – 5:30 p.m.
This panel will include a wide-ranging discussion of the role of insurance in the electrical supply industry. Starting with the basics of what insurance ‘is’, why it is needed, and some practical examples, the session will cover the relationship between insurance and maintenance management, failure rates, condition monitoring, asset management, and test/inspection.
So, please bring your questions about insurance, how it may affect you, and strategies to help your organization minimize risk and improve grid resiliency.

Problems, Solutions, & Advances in Windfarm GSU Transformer Operational Issues
April 15, 2:45 p.m. – 6:00 p.m.
Small pad-mount generator step-up transformers connect electricity generated from wind and solar power which eventually reaches the bulk electric grid. But these renewable environments are contributing to issues that can sometimes impact reliability. This session will look at studies conducted by AWEA and Doble on the gassing behavior of some windfarm GSU transformers proposing dissolved analysis guidelines. There will also be presentations on: partial discharge detection and corrective measures; windfarm generator step up (GSU) technologies and harmonic issues; as well as changes in the pad-mount transformer design for renewable applications. A series of panelists will provide a holistic approach to the some of the challenges posed by windfarm generator step-up transformers.
