ABSTRACT: Today, energy is a vital component in the functioning of a hospital.
Hospital technical facilities have several types of technologies, these include
appliances for use; examination apparatus. So, for Quality Health Care in a
hospital, there is a need to ensure the proper functioning of hospital equipment. In addition
to the required maintenance as specified by the device manufacturer, the quality of the electrical
energy across the device must be ensured. This article is an analysis of the
quality of electric energy at the substation of National Hospital of Niamey.
Thereby, the data collection, followed by the data processing and analysis
revealed the parameters characterizing the quality of electrical energy across
the substation. Our studies have shown that the substation is underutilized as
the maximum inrush current is less than half the available current. The current was consumed by the three phases
has resulted in a strong current unbalance
(230 A).
However, the current unbalance and the voltage amplitude, are admissible accordingly base on EN50160 standard.
Furthermore, the harmonics voltages present in this medium are in the accepted range
(1.8%) according to IEEE 519 standard. However, the fundamental frequency does
not meet the standard, but the difference obtained has no adverse effect.
