Influence on the Electromagnetic Compatibility of the Configuration of the Neutral in Grounding Systems for Hospitals

Abstract

This research analyzes the impact in the electromagnetic compatibility that the configurations of the neutral of grounding systems have in hospitals. The results herein propose a consistent standard model as the basis for future regulations to provide consistent guidelines for designing the power and telecommunications networks in hospitals, reducing the undesirable low frequency radiation exposure and improving their operations and maintenance. An experiment was carried out in two hospitals with different neutral configurations, so that the comparison could be validated. The outcomes of the simulation are presented and discussed, checking their compliance with International Electromagnetic Compatibility Normative. The TN-S neutral configuration is compared with the current standard design recommendations, showing a better performance in terms of network stability and electromagnetic compatibility. This study tries to justify the implementation of a design practice for the grounding system of hospitals which improves the management of the installation, its safety and durability.
