Abstract:
With theoretic analysis, lab experiment and engineering application, it is indicated that the SZJ grounding system is a new type grounding system which distinctly reduces the grounding impedance of grounding grids, especially of grounding grids in the zones with high-resistivity or grounding grids with scanty area. The design and calculation method for application of SZJ grounding system is also studied.
