Corona Discharge Power Losses Measurement Systems in High- and Extra-High Voltage Transmissions Lines

Abstract

In paper present the problem of non-contact measurements of the electric field is very relevant. Such measurements are necessary for remote monitoring of powerful power plants, including power line parameters such as discharge to the corona. In the paper the sequence of calculation power losses of corona discharge is presented. The power losses of corona discharge for extra high voltage transmission lines are calculated. In the work, a system for determining power losses per crown is introduced, the principle of operation of which is based on modern optical means for measuring electric field strength. Shown on the example of really working lines are the values of power losses per crown.
