Transmission network, Technical losses, Joule's losses, Corona losses, Leakage losses.

Technical losses arise by known physical electricity effects and it is not possible to eliminate them effectively. The paper deals with the 1st version of software tool for technical losses of transmission system lines calculation. The inputs are line parameters and measured data databases from control system of the Czech transmission system operator (ČEPS company). Outputs are Joule?s losses, corona losses and leakage losses for each transmission line. The paper also includes description of input databases structure, calculation result files and computing algorithms.
