Design of substation grounding grid in CFETR. [PDF]

Sci Rep
This paper aims to propose a method for the design of the substation grounding grid in China Fusion Engineering Test Reactor (CFETR). In order to evaluate the safety of the grounding grid, Electrical Transient Analysis Program (ETAP) was used to simulate the fault current, contact voltage, and step voltage, and the results are compared with theoretical

Grid-Ground Electrode in Two Layered Non-Homogeneous Ground

7th Symposium on Applied Electromagnetics SAEM`18: Conference Proceedings, 2019
In this paper, a procedure including using of the Green’s functions for a point source in multilayered media for the electric scalar potential and the Method of Moments-MoM for analyzing described problem is adopted. The approach provides generating Green’s function of the point source for arbitrary number of homogeneous layers. Also, it is possible to

Research Advances of Soil Corrosion of Grounding Grids [PDF]

Micromachines, 2021
A grounding grid plays the role of discharging current and balancing voltage to ensure the safety of the power system. However, soil corrosion can damage the grounding grid, which then can endanger the safe operation of power system. This paper reviewed recent research advances of soil corrosion of grounding grid.

Noncontact electrical metrology of Cu/low-k interconnect for semiconductor production wafers

, 2011
We have demonstrated a technique capable of in-line measurement of dielectric constant of low-k interconnect films on patterned wafers utilizing a test key of ~50x50 \mu m in size. The test key consists of a low-k film backed by a Cu grid with >50% metal
