Impulse Impedance of Grounding Grids
IEEE Transactions on Power Apparatus and Systems / Technical Operations Committee, 1980A 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.

On the Concept of Grounding Impedance of Multipoint Grounding Systems
IEEE Transactions on Electromagnetic Compatibility, 2014An N-port equivalent circuit approach is adopted to model a multipoint grounding system, N being the number of injection points. A methodology is proposed to determine the parameters of the N-port equivalent circuit from either numerical simulations or experimental measurements.

Portable Grounding Impedance Meter Based on DSP
IEEE Transactions on Instrumentation and Measurement, 2014A new grounding impedance measuring system based on digital signal processor (DSP) platform was developed. The low-cost portable device includes a built-in voltage impulse generator, nonvolatile memory for storage of measured current and voltage waves and a graphical display for fast data visualization.

Outdoor ground impedance models
The Journal of the Acoustical Society of America, 2011Many models for the acoustical properties of rigid-porous media require knowledge of parameter values that are not available for outdoor ground surfaces. The relationship used between tortuosity and porosity for stacked spheres results in five characteristic impedance models that require not more than two adjustable parameters.

A Generalized Grounded Impedance Simulator/Grounded Impedance Scaling Circuit with Electronic Tuning
2018 5th International Conference on Signal Processing and Integrated Networks (SPIN), 2018This research paper proposes a new circuit configuration which can act like a grounded impedance simulator/grounded impedance scaling circuit. The presented configuration can simulate electronically tunable grounded resistance/capacitance/inductance/FDNR and also work as a grounded impedance multiplier circuit, which can scale-up/scale-down the value ...

Impedance of surface footings on layered ground
Computers & Structures, 2008Traditionally only the static bearing capacity and stiffness of the ground is considered in the design of wind turbine foundations. However, modern wind turbines are flexible structures with resonance frequencies as low as 0.2 Hz. Unfortunately, environmental loads and the passage of blades past the tower may lead to excitation with frequencies of the ...

Cable system neutral grounding impedance
Electrical Engineering, 1935Determination of the permissible neutral resistance or reactance for the grounding of cable systems for 3 phase power supply is considered in this paper. The theory of overvoltages which may arise as a result of lative action is discussed, and a description of the method for calculating these voltages is given.
