Electrical distribution systems employ varied voltage levels to efficiently convey power from generation sources to end-use applications. A specific range, typically spanning from 1,000 volts (1 kV) to 100,000 volts (100 kV), occupies a critical middle ground. This level is strategically utilized to distribute electricity over moderate distances, serving industrial facilities, commercial buildings, and residential areas. An example of its application includes the distribution network supplying power to a small city’s substation, where it is subsequently stepped down for local use.
This intermediate voltage range plays a significant role in minimizing transmission losses and optimizing infrastructure costs. By transmitting power at this level, the current is lower than at lower voltages for the same power level, thereby reducing resistive losses in conductors. This approach enables efficient delivery of electricity, particularly in areas with moderate population densities or industrial concentrations. Historically, the adoption of this voltage range has allowed for the expansion of electrical grids and the electrification of diverse regions, driving economic growth and improved living standards.
