Speaker Bios:
Chris worked for General Electric for ten years with field engineering assignments in New Jersey, New York, Oregon, Pennsylvania, and Texas. He worked on industrial and utility power systems. Chris left General Electric in 1978 to take a position as Assistant Professor of Electrical Engineering Technology at the University of Pittsburgh. He taught motor, power system analysis, and control system technology courses for four years. From the University of Pittsburgh he went to Cornell University as Manager of the Electrical Department of Facility Engineering. Besides Cornell University's power distribution system, one of his responsibilities was Cornell's building and street lighting projects. Chris came to Arizona Public Service in 1985. He has been project engineer and manager of several high voltage substation projects. In recent years he has been working with APS' industrial and commercial customers, particularly with power quality problems.

C. William (Bill) Russell joined SRP's Power Quality Team as a Senior Engineer in 1997. Current responsibilities include power quality investigation and positive interaction with customers to secure the SRP commitment to quality. Prior to joining SRP, Mr. Russell was employed as a power quality specialist in the Phoenix area. Mr. Russell is skilled in power quality mitigation as well as investigative techniques, and has received certificates of accomplishment involving the National Electric Code. In addition, Mr. Russell has a broad background in the electronics field specializing in “side-looking” radar engineering. Mr. Russell holds a Bachelor of Science Degree in Electrical Engineering and is an active member in the Arizona Power Quality Association.

Dan Goodrich is a Supervisor in SRP's Electric System Operations group. Prior to working in SRP's system operations group, Dan led SRP's Y2K compliance and testing program. Dan has also held positions in system protection and system planning. Dan graduated from Arizona State University with a B.S.E degree in Electrical Engineering.

Scott Anderson is a Senior Engineer in SRP's Power Quality group. Scott holds Bachelor of Science degrees in Industrial Engineering & Management and Electrical & Electronics Engineering from North Dakota State. Prior to joining SRP, Scott worked in Motorola's Semiconductor Products Sector as a Facilities Staff Engineer. Scott is a registered Professional Engineer (PE) in Arizona.

Michael F. Stringfellow, Ph.D., P.E. is Chief Scientist for PowerCET Corporation. Prior to joining PowerCET he 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.
