Abstract: To accommodate the growing demand for electricity, a novel transmission line design has been proposed. This proposed structure must undergo rigorous evaluation to ensure it complies with existing safety standards. As magnetic field and electric field are crucial for the safety of systems and their surroundings, the proposed line must adhere to established limits. This paper presents a comparison of the electric field generated by a newly proposed unconventional overhead line compared to a conventional line where electric field is calculated for each sub-conductor individually. The results demonstrate that the unconventional transmission line exhibits a more favorable electric field profile compared to the conventional line.

In large to medium-sized cities in the US, the highest voltages typically found in the power distribution and transmission systems are as follows:
- Transmission Lines: These are the high-voltage lines that transport electricity over long distances from power plants to substations near populated areas. The voltages for transmission lines can range from:
- 69 kV (kilovolts)
- 115 kV
- 138 kV
- 230 kV
- 345 kV
- 500 kV
- Up to 765 kV in some areas
- Sub-transmission Lines: These lines carry electricity from the high-voltage transmission system to the distribution substations and have voltages typically ranging from:
- 34.5 kV
- 69 kV
- 115 kV
- Distribution Lines: These lines deliver electricity from substations to consumers and generally operate at lower voltages. Common distribution voltages include:
- 4.16 kV
- 13.2 kV
- 13.8 kV
- 25 kV
- 34.5 kV
The specific voltage levels can vary depending on the region and the utility company managing the electrical infrastructure. The highest voltages, especially those above 230 kV, are generally found in the transmission network, which is designed to efficiently move large quantities of power over long distances.

George W. Bush Presidential Library and Museum
The George W. Bush Presidential Library and Museum, located on the campus of Southern Methodist University in Dallas, Texas, was designed by architect Robert A.M. Stern. The library was dedicated on April 25, 2013, and it serves as the official library and museum for the 43rd President of the United States, George W. Bush.
Robert A.M. Stern is a prominent American architect known for his work on various projects, including academic buildings, museums, and residential structures. His design reflects a traditional and monumental architectural style that combines elements of classicism with contemporary design features. The library, located on the campus of Southern Methodist University in Dallas, Texas, was opened to the public in 2013.
Here are some features of the Stern design:
- Neo-Classical Style: Robert Stern’s design for the George W. Bush Library draws inspiration from classical architectural elements, particularly evident in the grandeur of its facade. The building features symmetrical lines, grand columns, and a sense of balance and proportion reminiscent of classical architecture.
- Materials: The exterior of the library is clad in Texas Cordova Cream limestone, which gives the building a timeless and elegant appearance. The use of this indigenous stone connects the library to its Texas roots while also conveying a sense of permanence and strength.
- Grand Entrance: The entrance to the library is marked by a grand portico supported by tall columns, evoking the imagery of ancient Greek and Roman temples. This creates a sense of importance and significance befitting a presidential library.
- Light-filled Interior: Inside the library, natural light floods the space through expansive windows and skylights, creating an inviting and uplifting atmosphere. The interior spaces are designed to be open and airy, with high ceilings and ample room for exhibits and displays.
- Landscape Design: Surrounding the library is a carefully landscaped campus that includes native Texas plantings, walking paths, and outdoor gathering spaces. The landscape design complements the architecture of the building and provides visitors with opportunities for reflection and relaxation.
We refer to him as American Vitruvius, given his influence on the architecture of so many educational settlements; reflecting classical elegance with contemporary functionality.
