Gradation project
My graduation is electric power distribution of a compound including buildings, villas, mosque, school, administrative building, market and street lighting
My instructor is Prof. Dr. Hanafy Mahmoud Ismail (from ain shams university)
1-Lighting design using Dialux software
· Dialux software: it is a program used for indoor, outdoor and street lighting.
· Inputs to the program: area, type of luminaries, required lux
· Output of the program: installed wattage, actual lux
2- Electrical design using excel sheet
· We use excel sheet to calculate the current, rating of circuit breaker, cable sizing,
· loading of light and sockets lines and loading of each phase
· Input to the excel sheet: installed wattage, power factor
· Output of excel sheet: C.B. rating, cable size
3- Writing detailed calculations in a word file
· Write all the calculations done in the excel sheet with the cable and C.B. codes (from catalogue).
4- Drawing the output using AutoCAD software
· Draw the layout including all sockets and luminaries and expressing the lines of lighting and sockets.
5- Single line diagram
· Draw the single line diagram of riser of each individual building
6- Planning of the area
· connect coffrees with pillars then connecting pillar to the distribution transformer
7- Check test
· make two tests to check that the system is approved (voltage drop test and short circuit test using Ecodial software)
8- Transformer connection
· We connect the distribution transformers in rings connected to the distributer which is connected to the medium voltage substation
