Integrated grounding systems: an unavoidable opportunity for users in urban and industrial areas

In the IEC approach, a global ground system by definition ensures the safety of interconnected MV / LV ground facilities, but the utility only can validate its existence. An integration between adjacent ground systems of users, such as in urban and industrial areas, assists to ensure that the safety conditions prescribed by the standards are met regardless of requiring recognition from the utility. This solution can contribute to promote the upgrade to the global ground system with the final adhesion of the utilities overcoming the problem of validating the global ground system and promoting the common interest of safety.
