Abstract :
This paper deals with common mode current and voltage produced by transients on grounding grids. A model of the grounding grid and the cable connecting two grid nodes is developed. The TLM numerical technique is adopted. This model permits the EMC analysis of common mode current in installations for adequate protection devices.
