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.
