Paper presents a calculation of the electric field distribution around the 400 kV transmission lines in power system of Bosnia and Herzegovina (B&H). Method of equivalent charges was used for the calculation of the electric field at arbitrary points in the vicinity of high-voltage transmission lines. Transmission lines with standard tower's dimensions, as well as lines with reduced (compact) tower's...
In this paper an attempt is made to study accurately, the potential and electric field distribution for different types of ceramic disc insulators used for high voltage transmission and distribution systems. The computer simulations are carried out by using a commercially available software package. The potential and electric filed results obtained for the actual insulator profiles for three types...
Corona is an important aspect which influences the design of transmission lines and electric equipments. With the increase of altitude and voltage grade, the corona performance of equipments becomes more complex. First, this paper explains electric field distribution around the overhead multiple conductors is consistent to one of multiple conductors in the corona cage; then according to the test data...
This paper describes a novel method to detect the electrification state of ultra-high voltage transmission lines based on electric field measurement method, which involves measuring the electric field at points in the vicinity of transmission lines and computing the electric field strength at the same points according to charge simulation method. A power frequency electromagnetic field strength measurement...
Potential and electric field distribution along 1000 kV AC transmission line composite insulator are analyzed in this paper. A sub-model approach based on finite element method (FEM) is applied in calculating the potential and electric field distribution along the insulator under clean and dry conditions. Using this approach, three dimensional (3D) electrostatic models taking into account the grading...
