Topic: "Case Studies 2014"

Location: SRP Information Services Building (ISB), 1600 N Priest Dr, Tempe, AZ 85281

A collection of Case Studies from APQA Members.

Case Study 1 -
Topic: Lightning Currents in Unprotected Structures
Speaker: Dr. Michael Stringfellow, PowerCET
Summary: The paper uses computer modeling to calculate the currents and voltages on services in buildings that result from lightning strikes to metallic roof penetrations such as furnace vents and chimney flues. The results show that both electric wiring and gas piping systems may be damaged from the resultant stresses. One surprising conclusion of this study is that inductive voltage drop along conductors struck by lightning likely contributes far less to flashover risk than is typically assumed.
Biography: Prior to joining PowerCET, Dr. Stringfellow held the positions of Chief Scientist and Director of Research for EFI Corporation. Other experiences include 9 years with the Electric Supply Commission (Eskom) in South Africa, and work with Kearney National and Atlantic Scientific Corporation. His research has focused on lightning surges and their impact on commercial and industrial facilities, and utility transmission and distribution systems. Dr. Stringfellow has published numerous articles and research papers during his distinguished career. He is a member of IEEE and is an active member on several committees. He earned a B.S. Honors Degree in Physics from the University of London and his Ph.D. in Atmospheric Electricity from University of Durham.
