Determination of the Induced Voltages by 220 kV Electric Overhead Power Lines Working in Parallel and Narrow Routes. Measurements on the Ground and Mathematical Model

The paper presents the measurements that the author has done in the South West area of Romania for the 220 kV double circuit overhead power lines having a passive circuit and an active one. It also describes a mathematical simulation for determining the induced voltages by the active circuit into the disconnected one. The measurements are compared with those obtained through calculations in order to validate the mathematical model, becoming a useful tool for professionals in electric high voltage overhead power lines. Key-words: electromagnetic interference, high voltage, induced voltage, electric capacity, mutual inductivity.
