Impulse Impedance of Grounding Grids

IEEE Transactions on Power Apparatus and Systems / Technical Operations Committee, 1980
A method and an empirical formula to calculate the inductance of square grounding grids fed at either centre or one of the corners is presented. Empirical formulae for the effective area and impulse coefficient for centre fed and corner fel square grids are determinel.

The Tapered Impedance Half-Impulse Radiating Antenna

IEEE Transactions on Antennas and Propagation, 2021
In this article, we introduce the tapered impedance half-impulse radiating antenna (TI-HIRA). This innovative version of the HIRA allows the direct connection of COTS, $50~\Omega $ generators to the antenna, without requiring external transformers and without using the large, blocking, plates that would be required in the traditional constant ...

Impulse Impedance Measurements of Lightning Protection Earthings

2019 IEEE PES GTD Grand International Conference and Exposition Asia (GTD Asia), 2019
Lightning protection earthing systems should be tested at currents with time parameters similar to those of lightnings. A method and definition of a measured value of impulse impedance are introduced. The impulse impedance was determined by a quotient of voltage drop on the tested earthing to a value of current in measure circuit. The usefulness of the
