Investigation of Power Quality in Health Care Facility

Abstract

Modern healthcare facility has unique power system requirements as the power quality and reliability is a crucial feature to maintain the critical services such as surgical operations, intensive care units and other critical services. Healthcare facility has become dependent on the quality of electrical supply. This paper aims at assessing the level of harmonic pollution to a health care facility. The investigation focus on assessing the level of THD on this healthcare facilitates. Further discussion includes various ways of reducing harmonics in health care facilities from the study it was found that although there are numerous amount of harmonics producing equipments exist, the total harmonics distortion is still within the recommended level as advise by IEEE 519. There is also clear evidence that active filter using active harmonics conditioner play an important role to this instance.
