A transmission high voltage engineer and safety professional, Dianoush Emami is a former electrical engineer at Bechtel Power Corporation. Based in California, Dianoush Emami has worked with other electrical engineers in developing energy infrastructures like nuclear power plants and has calculated voltage drops of electrical transmission systems.
With reference to the current standards, voltages below 300 kilovolts are categorized as high voltages, voltages ranging from 300 to 765 kilovolts are categorized as extra high voltages, while 765 kilovolts is an ultra-high voltage. Often, electrical energy is generated at a lower voltage of around 11000 kilovolts and later stepped up to higher voltage, such as 132 kilovolts, 220 kilovolts, or 400 kilovolts prior to transmission. Raising the voltage of transmitted energy comes with a lot of benefits, although it increases radio interference, and requires a proportional increase in the height of towers used for transmissions.
By increasing voltage, the current is reduced, and this results in a proportional reduction in the volume and size of the conductor required for transmitting a particular amount of power, and this, in turn, reduces expenses spent on conductors. Extra high voltage reduces in-line voltage drops, which in turn improves in-line voltage regulation. With extra-high-voltage, a line can be easily tapped and extended. In addition, extra-high voltages increase transmission line efficiency.
