نظم توزيع القوى الكهربية - مقرر اختياري للفرقة الرابعة قوي

In the current state of the art in the supply of electrical energy, there is an increasing need to make the overall electrical systems in residential building, large commercial buildings and in industrial sites etc -
 more energy efficient, with better energy management;
 safer in all aspects (including personnel safety, fire and equipment safety);
 of adequate power quality with regard to harmonics and over-voltages;
 able to accommodate modern information technology systems;
 being compliant with the new EMC and EMI regulations for electrical systems;
 providing monitoring systems to assess the condition of the electrical installation.
This course aims to address these issues. To fulfil this purpose, the following contents are arranged: overview on power supply to end users, mainly including industry plants and residential buildings; switchboard selection and design for a specific applications; selection of cable sizes with the consideration of current rating, and voltage drop under different operating conditions, such as different ambient temperature and different bundling etc; study on and selection of distribution transformers; Fault current calculation for three-phase symmetrical fault; overcurrent protection for power distribution circuits; earthing or grounding system study; lightning protection system study; power quality and reactive power compensations issues etc.
