A California-based electrical engineer, Dianoush Emami has significant experience designing power plants. Dianoush Emami has set up high-voltage transmission and electrical distribution systems that provide a consistent, safe energy source.
Transmission lines carry energy in large quantities from generating stations to substations, which can be distributed to individual businesses and households. The design and capacity of such lines vary widely, ranging from 44,000 volts to more than 750,000 volts.
Because of the high load capacity and extremely high voltage, transmission lines do not have an insulating sheath, as with the smaller loads involved with electrical lines and poles from substations. Instead, the air around the lines acts as an insulator, making it critical that nothing comes close to them, such as a tree branch, that might cause serious fire and outage. Because of the high voltages, a tree does not even need to touch the line for an electric arc to occur.
For this reason, all transmission lines are set up with right-of-ways that prevent vegetation from being planted in the vicinity. In addition, this cleared area enables personnel to access lines for inspections, repair, and maintenance.
