Description East of Wichita, Kansas is a newly constructed 69-kV transmission line which is now being built for 138-kV operation. Note the new H-Frame which is equipped temporarily with stringing hardware on the ends of suspension insulators and the tension stringing equipment for line conductors below. Line stringing is not done one conductor at a time; this would cause unequal bending movements in structure supports and would cause catostropic failure at attachments.Instead, all conductors, including static or Overhead Ground Wires (OWGs) are strung in concert, avoiding any unequal bending or snagging which might endanger personnel or traffic on the highway paralleling this newer line.Original line is a wooden single pole Z-structure circuit operating at 69-kV.Switchyard is located east of Wichita, Kansas on U. S. 75. It is operated by Westar-Energy, Inc. of Topeka.
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.
