Characterization of Voltage Dips and Other Types of Electrical Faults in Cameroonian Hospitals Using the Itic Curve

Abstract

Energy instability issues are central to Cameroon’s 2030 development strategy. This Central African country aims to ensure an energy supply that can provide quality healthcare services to its population by 2035. In order to predict energy quality in its hospital facilities, a University Research Center in Energy for Health (CURES) has been established within the National Advanced School of Engineering of Yaoundé. Using a set of data collected by CURES from several hospitals in Cameroon, this paper proposes a classification of electrical faults using the ITIC curve, which highlights the issue of the mismatch of devices designed based on European standards. The projections of data collected during various electrical audit campaigns in several hospitals in Cameroon onto this curve, allow for efficient detection and identification of disturbances that cause the premature destruction of biomedical equipment in the Cameroonian environment.
