Transmission Lines

Transmission Line basic process is to create the conditions so that the direction of transmission of electromagnetic energy transmission lines. Line transmission capacity by electromagnetic fields and circuits governed the various laws.

Transmission Lines

The maximum transmission power transmission line after consideration of all the factors of technical, economic and other determined. Therefore, improving the transmission voltage is high capacity or long-distance transmission of the main technical means, but also the main marker level of transmission technology development.

Transmission lines have primary protection and back-up protection of the points. There are generally two main protection longitudinal differential protections and three-current protection. In the EHV system now mainly uses high-frequency protection. There are distance protection backup protections, zero-sequence protection, direction protection.

Transmission Line the presence of external damage, icing, lightning problems.
