Transient Ground Potential Rise in Gas-Insulated Substations - Problem Identification and Mitigation
IEEE Transactions on Power Apparatus and Systems, 1982Transient ground potential rise, a phenomenon of 10-100 kV potentials with up to 10 ?s duration on the grounded enclosures of gas-insulated substations (GIS), may cause concern for personnel safety and problems for protection and control circuitry.

Transient Ground Potential Rise in Gas Insulated Substations - Assessment of Shock Hazard
IEEE Transactions on Power Apparatus and Systems, 1982Breakdowns and disconnect switch operations in gas insulated switchgear (GIS) generate short duration high potentials on the grounded GIS enclosures. These high potentials cause breakdowns between the GIS enclosures and other nearby grounded components, and have resulted in low voltage protection and control wiring failures and personnel shocks.

Influence of Ground Potential Rise on Recloser Control Broad in Distribution Lines
2006 International Conference on Power System Technology, 2006This paper presents the numerical analysis method of current distribution electromagnetic fields, using grounding and soil structure analysis (CDEGS) software to interpret apparent resistances field measurement result. The steepest descent method is the function of least-square criterion which is adopted to translate and to explain the field measured ...

Probabilistic Assessment of Ground Potential Rise Using Finite Integration Technique
IEEE Transactions on Power Delivery, 2018The behavior of grounding systems against waves with high-frequency content such as lightning or very fast transient overvoltages is completely different from the steady state. This paper presents a more flexible model of a grounding system with respect to frequency dependency of electrical parameters of soil and moisture variations using the finite ...

Calculation and Analysis of the Impact of Ground Potential Rise on 10kV Lightning Arrester
2019 IEEE Sustainable Power and Energy Conference (iSPEC), 2019As the capacity of the power system continues to expand, the risk of explosions in 10kV arresters is increased due to ground potential rise. This paper analyzes the mechanism of the 10kV arrester affected by ground potential rise, and determines that the arrester explosion caused by the insufficient flow capacity is the main problem to be prevented at ...

Ground potential rise influence near HV substations in urban areas
16th International Conference and Exhibition on Electricity Distribution (CIRED 2001), 2001When the grounding system of a high voltage substation is connected to uncoated metallic shielded cables, they act as a part of the grounding system, and have large influence on the potential distribution around the substation. National and international regulations define the potential contour 430 V as a border of the GPR zone of influence on ...
