Description This particular tangent pole of the former Mitchell-Tyndall, South Dakota Northwestern Bell Toll Lead, has an higher pole to obtain clearance in order for a drop to cross a county highway. This line was one of two which were being considered for the nation's first nomination of an open wire line, in situ, by D. G. Schema and The Electric Orphanage during the years 1979-1982. This line was wrecked out in 1982, however many artifacts from this line were preserved. The Tilford, South Dakota line was preserved in its entirity which can be seen west of I-90 at the Tilford Exit in the Black Hills of South Dakota. Note the side bracket construction which served some exchange lines for nearby farms. They shared the bottom portion of this lead with the most important toll carrier circuits on the top arms.For the full story of this nomination, go to Song of the Open Wire website and The-electric-orphanage.com.
Douglas G. Schema, Topeka, Kansas Member Since November 2011 Artist Statement Administrator of The Electric Orphanage, a non-profit historical preservation project highlighting the technological evolution of the electric power distribution and transmission industry, street and highway lighting technologies. Open wire telecommunications technology, which provided the early foundation for power system design, is also a part.
Mr. Schema holds two master's degrees and has worked in the telecommunications industry. His dual electric power and telecom background has facilitated contacts throughout the United States in order to preserve the heritage of the industries for which he has worked.
Utilizing 20+ years of experience with library science and bibliographic research (in the medical, allied health, scientific, engineering, public policy and state and federal document divisions), he has a significant grasp of the technical literature sources.
His artwork topicality and specialties ARE the electric and telcom industries specifically; having devoted over 50 years of work to advance their aims. Each piece is constructed with both creative care and technical expertise, to guarantee a high degree of technical accuracy and authenticity. This is a hallmark of both his artwork and photography. His artwork takes the form of both pen and ink drawings or highly detailed renderings in pencil.
Among the many utilities for which his works have been commissioned or requisitioned, are the Los Angeles Department of Water & Power, Southwestern Public Service Company/Xcel Energy, Tri-County Telephone Association, Northwestern Bell and many other organizations. He has had continuous relationships with nearly all the U. S. investor-owned utilities and hundreds of smaller municipals, public power districts, electric distribution and G&T cooperatives since the 1960s. Every year, the artist attends major conventions of the IEEE/PES, IES of NA, Investment Recovery Association, and other industry-related groups.
"The Song of the Open Wire" will initiate a host of upcoming websites in this technological arena of the utilities. Anticipate additional sites which will envelope both outdoor lighting as well as T&D/Substation technical topics and processes.
