Abstract

Abstract:
Early power plants were small and capable of generating electricity only for its immediate
surrounding area. As the demand for electricity increased, electric utilities built larger and
more efficient generating stations that replaced small ones. Since new plants were no
longer adjacent to their load centers, transmission lines became necessary in transmitting
power along hundreds of miles from power plants to local distribution areas.
The rapid industrialization in the 20th century made electrical transmission lines and grids
critical parts of an economic infrastructure. Engineers design transmission networks to
transport energy efficiently by putting into consideration some economic factors, network
safety, and redundancy. Overhead transmission lines are the most commonly used means
of transferring power from one location to another without interruption. Historically, A.C.
systems have dominated transmission because it transforms very high voltages into useful
lower ones but recent developments in power electronics have resulted in competitive
distances and line construction and stringing costs are significant [1].
In this study, the researchers find the need to investigate the performance of medium
three-phase transmission lines with the aid of the TQ NE9080 Transmission line
Simulator, an experimental facility at the Electrical Engineering Laboratory of the
MAPUA Institute of Technology, Philippines. The study also includes
comparison/analysis on the performances of the different types of medium transmission
lines.
