Paul Griffin enjoys diagnostics. As vice president of consulting and testing services at Doble Engineering Co., he has learned to get as much data as he can, assess the accuracy, and evaluate. “Let the data lead you to the correct answers,” Griffin said.

With 34 years in the power industry, Griffin has seen many transformer problems and the tests used to detect them. Since he started his career in the Doble Materials Laboratory, he has gained hands-on experience performing and evaluating these tests.

Now he uses that experience to share his knowledge with the collective community. Griffin presented this week at the 2014 Life of a Transformer Seminar on Feb. 4 in Lake Buena Vista, Florida. His presentation covered the general properties of dielectric, insulating fluids used in electrical equipment. It provided in-depth information on each of the current fluid choices available in today’s transformer market. Basic properties along with the advantages and disadvantages of each fluid were discussed. Particular attention was paid to the newest fluids class, natural esters. The maintenance and use of these fluids was also reviewed. This included the storage, treatment and transfer of fluids. Finally, the current industry standards and diagnostic testing were presented.

“Oil testing provides the most cost-effective diagnostics for transformers and provides the most critical information that can be acquired while a power transformer remains on-line,” Griffin said. “These tests allow for the initial assessment of transformer health and can be effectively used to help manage problems that are detected.”

Griffin has presented many sessions including laboratory diagnostics and condition assessment. He teaches several courses including Transformer Insulating Fluids, Asset Health Review and Transformer Assessment using Laboratory Diagnostics.

He almost stumbled upon his love for diagnostics and for Doble. After he received his B.S. at the American International College and M.S. from the University of Rhode Island, he thought he would try Doble for a year, “The next thing you know, 34 years have gone by,” he said. “Doble is a great company to work for because of the unique relationships we have with our customers.”

In 34 years, Griffin has held various positions including Laboratory Manager and Vice President of Laboratory Services. Griffin has published more than 50 technical papers pertaining to testing of electrical insulating materials and electric apparatus diagnostics. He is a Fellow of ASTM and a member of Committee D-27 on Electrical Insulating Liquids and Gases. He was formerly ASTM Subcommittee Chairman on Physical Test, ASTM Section Chairman on Gases in Oil, and the Technical Advisor to the U.S. National Committee for participation in the International Electrotechnical Commission, Technical Committee 10, Fluids for Electrotechnical Applications. Griffin is a member of the IEEE Insulating Fluids Subcommittee of the Transformer Committee.

In his bit of spare time, he enjoys playing tennis and spending time with family.
