I created many projects during my studies in college, where I made a loudspeaker from some simple electronic devices such as transistors. I also created a complete study project for a medium voltage pressure network, studying loads and voltages, measuring the efficiency of energy transfer, and calculating electrical losses. Also, in one of the projects, a study was conducted of the loads of some university hospitals, and a system was created to protect the hospital from all types of possible electrical faults by maneuvering and disconnecting the smallest number of loads during the occurrence of the fault. My graduation project was about saving electrical energy consumption in large institutions and companies, by auditing and studying the loads, and by analyzing these loads, certain measures are taken to reduce electricity consumption inside this building, and indeed we obtained an excellent result in the end by saving more than 50 percent of consumption.
