Joseph LEVODO, a student at the Department of Electrical Engineering and Telecommunications, supported its report of end of studies in front of a jury to the ENSP on July 10th, 2015. His research took place during an academic internship of five (05) months at the CURES. He has interested in the problem of power protection in the Cameroonian district hospitals.

The study has consist to investigate the various means used for electrical protection in our district hospitals, to notice the limits thereof by mentioning the electrical risks and suggesting solutions for improvement. To achieve this, three energy audits in district hospitals in different regions of Cameroon were carried out.
These descents allowed to do an inventory of the various protection devices and electrical equipment which are used in these hospitals, and to measure the soil resistivities and grounding resistances.
From these data and using different analysis algorithms, we obtained the following results: the Cameroonian district hospitals do not have safety devices against electric shock, power surges and fires ; exposing people to the risk of electrocution, electrification or fibrillation and equipment to the risk of overvoltage or lightning.Most of these district hospitals have as he neutral system, the TT system, which does not ensure continuity of service in case of a fault
To resolve that problem, additional devices were sized to optimize power protection in these hospitals and solutions have been proposed for these hospitals can pass neutral IT system that ensures continuity of service during the appearance of the first fault.
