Orientation report

Order Description orientation report thats need additional words in introduction. also can you change the structure to an academic report also the general words to an academic words. introduction This report aimed to identify the social and technical process that connected to the meter section. 1. Installation section There are three units in installation section: • Technical specification and qualification • Building permit complex • Service connection unit • Building permit complex unit They responsible about gives permission for the electrical and water installation in the building for the consultant to start. Process in general starts from consultant to municipality, KM, study this application by KM engineers and approved. This unit consist of water department and electrical department. Electrical department: Miner section: for all villas and any cut-out less than 350A and Maximum demand 210kw. Major section: above 350A. In building permit the Process consists of planning study and installation study. Planning study process: A. Method of connection (MOC) B. Supply direction C. Connection size A. Method of connection (MOC) There are three types of connection: Firstly, service cabinet which the connection in this method starts from network to the cut-out and to the meters in same cabinet then to main switch board. If the cable size 4core x120 mm2 or more then the cable it will be from the C/O direct to MSB and separate cable to the meter. maximum c/o for service cabinet is 200A with a cable size 4core x 120mm2. Secondly, Electric room there are two types of electric room namely, electric room one point supply the maximum C/O here 350A and electric room two point supply with A maximum 700A by add both of them. . Lastly LV panel if the C/O more than 700A so they need for LV panel which the connection here from transformer to LV panel then to building. B. Supply direction Supply direction means that direction for cabinet service, electric room and LV panel by north, south, east or west C. Connection size c/o Cable size 50A 4core x16mm2 75A 4core x 16mm2 100A 4core x 35mm2 or 4core x 50mm2 150A 4core x 70mm2 or 4core x 95mm2 200A 4core x 120mm2 250A 4core x 185mm2 300A 4core x 240mm2 350A 4core x 300mm2 How to calculate Maximum demand and C/O Example: Consultant gives loads as show below: AC W/HEATER COOKER GENERAL OTHER 50 10 4 26.7 0 So MD = (50X100%)+(10x30%)+(4x40%)+(26.7X60%)+(0X100%)= 70.26kw C/0= 70.26 X 1.64= 115.72A So C/O should be 150A Installation study process: When the consultant gets approve from municipality then they allow for him to upload electrical cad designs (SSP-Electrical layout- SLD) to let engineers check the installation. What they check in Cad designs (SSP-Electric layout-SLD) • SSP (Service Site Plan) 1. Compare the SSP design with the A01 (should be identical) 2. the method of connection, the supply direction and the service cabinet or the electric room should be close to the electric networks. 3. Pin in SSP should be same to the application. 4. MSB place and should be only one. 5. MD and C/O. • Electric layout 1. DB (distribution board) should be on in each floor. 2. Sockets and switches • SLD (Single Line Diagram) 1. ELCB (in wet place) 2. AC cable size 3. Balance between phases (yellow- red –blue) Water department Miner section: for any villa and the capacity for tank (800 gallons to 2000 gallon). major section: between (5000 to 125000 gallon) daily consumption. Installation and planning study process: A. Method of connection B. Supply direction C. Connection size A. Method of connection (MOC) For villa the connections start from water networks to the meter (which it should be close to networks with maximum distance 15 m) then from meter to the tank and from the tank to home. For a commercial building if the building more than 10 flats the connection should be form networks to main meter then to underground tank then to a pump after that to roof tank if the building more than 6 floors they should put (NRV-not return valve) and (PRV-pressure reducer valve) between the pump and the roof tank, after that from the roof tank to meters which it should be in each floor. The connection to the flats meters it’s like that (roof tank –pulp-meter-NRV -flat). If the flats less than 10 meters here the meters should be in underground. B. supply direction (north-south-west-east) C. Connection Size Daily consumption in gallons Pipe size in mm 800-5000 22 5000-10000 28 15000-20000 42 25000-60000 54 70000-125000 80 How to calculate Maximum demand Example: If there is a commercial building that had 10 flats. Each flat had two double room. What’s the maximum demand? If is double that’s mean two person in each room so in each flat 4 person each person = 0.4m3 for 1 flat 4x0.4=1.2m3 x 219.969= 317.0064 imperial gallons MD = 317.0016 x 10 = 3170.064 gallon so the meter size is 22mm. Service connection unit (Front SC line) before the conductor finish the building he should apply here for the electrical and water connection by online and upload all his attachments after he applied the unit should check all his attachments then they issue IN number which use to check his process. Also front line will issue the water no and electrical no. then it will go direct through GD EDWARD SYSTEM to (830) planning , internal inspector (753) , fees(754). Electric planning There are two units in electrical planning section namely distribution planning and service coordination. Service coordination process: Their responsibility for direct connection to the customers whatever they need either t-joined from the main network or main extension cable. Also they responsible about miner application such as supply relocation, supply reinforcement, temporary supply and add meter installation. When the unit gets any application like this they study the network in the area if is ok they give approve and send it to CSD for the payment then they send back to electrical planning after that transfer to construction. Distribution planning unit: They are responsible about scheme such as diversion, supply scheme and network reinforcement. Procedure of work Process for this cases starts from Building permit or the applicant To distribution unit firstly the engineer studies the case by study the network and make a proposal then make a draft proposal about how the connection will be from the network then send to draft man to design the drawing in AutoCAD then transvers to municipality and urban planning to get approve from them since they gets the approve directly the unit prepare costing and transvers it to CSD then send it back to DP to send it to construction. Constriction This section consists of four units namely: 1. Main extension unit 2. Reinforcement unit 3. Scheme 4. Civil unit Main extension unit They responsible about the connection to customer either direct connection or extend the cable from the main network. Reinforcement unit They responsible about reinforce the network by built a new substation for the area to reduce the load from the old substation there. Also add a new feeder if there over load feeder and cable diversion (11kv). Scheme unit If the connection to the customer not direct or main extension it will be scheme which they need to a new supply (substation) or diversion cable(low voltage) Civil unit They responsible about built the substation either public substation or privet consumer substation. Type of substation: 1. Indoor substation it could be one or two transformers 2. Outdoor substation one or two transformers 3. Package substation only one transformers Method of connection 1. Service cabinet If the cable size 4coreX35mm the connection will be from the main network to C/O in the cabinet then to the meter after that to MSB. If the cable more than 35mm it will be direct from the C/O to the MSB and there is a (CT) current transformer will be in the cable and connect it to the meter. 2. Electric room If the cable size more than 120mm so it should be electric room and the connection same to the service cabinet which by add CT. 3. LV panel The connection starts here from the networks to switchgears then to TX which it could be two or one transformer then connect to the lv panel and connect to the meter. Process in general Most of the application come through GD Edward system to the focal point in constriction then it will go to RO unit to get permission from municipality, urban planning, Ashgal and MOI. When they get the approve send it to an engineer to issue CWR (conductor work request) the conductor will starts his work after he finish from put the cable in trench he will apply for shutdown and he should finish the connection through 4 days in maximum. After that they will send it to CSD to continue the process and fix the meter.
