Abstract

This paper is about the measurement of parasitic capacitances (or inherent ones) between the power conductors and the earthed parts of an IT system. The measurements were conducted in an Operation Room, in a Hemodynamics center and in the Intensive Care Units (ICU) of a Brazilian hospital. Measurements in ten different experiments were also used with the objective of diminishing the capacitances in future installations, since they increase the risk of a microshock to the patient. From the present work, result orientations to minimize the capacitances to lower levels, which can be adopted by the professionals in charge of electric installations in hospitals.
