a 1. Design of a Sub-distribution Panel] Assume that you are required as an electrical engineer to design a sub-distribution panel in the final stage for an apartment that contains the following different Static Loads: a) Eight (8) Illumination circuits (single-phase, 220V, Total: 9kVA) b) Two (2) Socket circuits (single-phase, 220V, Total: 3kVA) c) One (1) Washing Machine (single-phase, 220V, 3kVA) d) One (1) Boiler (single-phase, 220V, 1.5kVA) e) One (1) Water Heater (single-phase, 220V, 3.5kVA) f) Three (3) Air conditioning (single-phase, 220V, 2.2kVA for each) g) One (1) Oven (three-phase, 380V, 12kVA) First, check the Single Line Diagram (SLD) given below: 4 x C mm 3 x BM (A) 3x B(A) 1 x B2 (A) 1x B3 (A) 1 x B (A) 1 x B (A) 1x B(A) 1 x B (A) 4xC mm 2 x C2 mm 2 x C3 mm? 2 x C, mm 2 x C3mm 2 x Comm? 2 x C mm 3 Oven Air Condition Boiler Socket Washing Machine Water Heater Illumination circuits
By the checking the SLD diagram given above, then: i. You are required to find the rated currents for each load (B4,C;). [To be able to do that, you should first complete the following table]. ii. You are required to find the rated currents (BM,CM) for the main feeder circuit. [To be able to do that, you should find the maximum rated current of the 3-phases. You can distribute the loads on the three phases such as each phase takes approximately the same load current]. Total Current Load Irated for each circuit ICB Ісв Calculated standard Cable Section Rating mm2 (A) Illumination Sockets Washing Machine Boiler Water Heater Air Cond. Oven Number of suggested circuits 8 2 1 1 1 3 1
Important notes: [The final point of this assignment will be considered based on the following points] ✓ Try to design the given electrical board as efficiently as you can. At some points, you need to do some searches to be able to give the practical design. ✓ You are required to show all the required calculations and details. ✓ You are required to provide me with all the used tables.
2. General Please select one small automation system (it could be from any system you see before, you worked with, or around you), try to study it, and describe its working principles providing the description of the system with its power and control boards. Besides, I will like it if you change the control circuit related to some better upgrades and suggestions to the system.
