Lightning Impulse Impedance and Surface Potential Distribution of 10 kV Distribution Line Tower: Field Test and Simulation

IEEE Transactions on Power Delivery, 2022
The impulse grounding performance of distribution lines tower is the key factor to lightning protection. Few field high-current impulse test researches are conducted on distribution line tower. In this paper, we used a mobile high-current impulse generator to conduct test on a 10 kV distribution line tower.

Research of mutual radiation impedance effect on surface vibration velocity distribution

2017 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC), 2017
Based on the lumped parameter theory of piezoelectric transducer, the mathematical relationship between mutual radiation impedance and surface vibration velocity distribution of the array element is established, and then the simulation experiments were carried out for a 5×5 planar array.

Distribution of current, surface impedance, and damping in superconductor coupled microstriplines

Technical Physics, 1997
The nonuniform current distribution in the transverse cross section of the coupled conductors of a microstripline made with superconductor films leads to a substantial dependence of the losses in the line on the relative position of the coupled strips.

Current distribution and input impedance of a circular loop antenna located on the surface of a gyromagnetic cylinder

2018 Days on Diffraction (DD), 2018
Electrodynamic characteristics of a strip loop antenna located on the surface of a gyromagnetic cylinder are studied using the integral equation method. The cylinder is aligned with the gyrotropy axis and surrounded by an isotropic magnetodielectric medium. A rigorous solution for the antenna current excited by a time-harmonic given voltage is obtained.

The input impedance of a thin dipole with sinusoidal surface current distribution by the Poynting vector method

IEEE Transactions on Antennas and Propagation, 1995
The input impedance of a thin (a/spl Lt//spl lambda/) center-fed dipole with an assumed sinusoidal surface current distribution is obtained by the Poynting vector method. It is shown that by retaining the surface current distribution rather than replacing it by the classical equivalent line current on the dipole axis, the Poynting vector method can be ...
