On the Concept of Grounding Impedance of Multipoint Grounding Systems

IEEE Transactions on Electromagnetic Compatibility, 2014
An 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.

Hybrid grounding of electrical systems

2016 Petroleum and Chemical Industry Technical Conference (PCIC), 2016
This paper will discuss the many different ways to ground medium voltage generators. Single source as well as multiple source units, either unit connected or bus connected, will be shown with preferred grounding schemes.

A Fault Section Location Method for Small Current Grounding System Based on HHT

China International Conference on Electricity Distribution, 2018
A fault section location method for small current grounding system based on Hilbert-Huang Transform (HHT) is proposed. When a single-phase grounding fault occurs in the distribution network, the transient zero sequence current uploaded by the FTU on the ...

MiniCheck: Efficient Fact-Checking of LLMs on Grounding Documents

Conference on Empirical Methods in Natural Language Processing
Recognizing if LLM output can be grounded in evidence is central to many tasks in NLP: retrieval-augmented generation, summarization, document-grounded dialogue, and more. Current approaches to this kind of fact-checking are based on verifying each piece

Grounding systems research: re-establishing grounded theory

Proceedings of the 35th Annual Hawaii International Conference on System Sciences, 2003
In the field of information systems (IS) there has been a growing trend away from a technical view of systems (with the system literally seen primarily in terms of the physical devices), to one that seeks to account for nontangible aspects such as cognition, culture, motivation and so on.

Grounding System Parameters and Expression of Ground Resistance

2016
In any electrical circuit network, the circuitry that provides a path between the parts of the circuit and the ground, is known as the grounding system. The grounding system is required for reliable operation of any electrical equipment including generator, transformer, power system tower, and other power system installation under fault conditions.

Ground-3D: A FEM CAD/CAE System for Ground Systems Analysis

Digest of the Fifth Biennial IEEE Conference on Electromagnetic Field Computation, 2005
A complete modelling of a grounding system made by ground meshes, connected or not in multilayer soil is presented. A 3D approach is used to model rods or wire conductors, grave layers and conductor plates that are commonly found in grounding systems.

Grounding principles and practice IV — System grounding

Electrical Engineering, 1945
Grounding of transmission and distribution systems is considered in this article, the fourth of five based on a series of lectures on the subject which was sponsored by the power and industrial group of the AIEE New York Section during the 1943–44 season.
