Abstract |
The purpose of isolated grounding systems is to protect own electrical facilities from the other grounding systems in order to avoid the potential interference between ground grid areas. But the physically close distances involved could lead to potential interference problems. The simplified equation for determining potential interferences based on the measured data under the case study grounding system is proposed in this paper. The results obtained with the equation to verify the accuracy have been compared with the results obtained from the CDEGS program. |
