Electrical safety in medical institutions "neutral electric potentiality system in hospitals"

This paper discusses the practical application of electrical protection and safety at medical institutions. Systems of neutralization and grounding are used with medical diagnostic and cure devices, which use very complicated electronics. These devices are especially sensitive to minimal transient potential differences which may have corresponding electromagnetic influence. On the other hand it is known that a sick person has lower body resistance towards electric current; an additional safety requirement is therefore needed. Structural schemes for neutral and grounding protection applications are described. This is in addition to the protection and safety measures currently used in physiotherapy and rehabilitation departments.
