There may be double line in the bus so that if any fault occurs in the one the other can still have the current and the supply will not stop. This project paper provides the synopsis assessment of all the systems existing 33/11 kV Dhaka Palli Bidyut Samity-1, Savar. Skills: AutoCAD , CAD/CAM , Solidworks , Engineering , Electrical Engineering. Designing of 6/8 MVA, 33/11 kV substations and 33/11/0. Grid substation of OPTCL 220/110 kV located at Kapilaprasad, Bhubaneswar, Orissa, India and a 11kV/420V Distribution Transformer Bay has been taken for case study. Completion certificate by M/s BES Europe Ltd. When it comes to project constraints such as limited-budget, fast-track schedule, extension works, complex modifications or rehabilitations, AK-AY Elektrik does it all from. single line diagram of 220/132/33 kv gss fatuha µ prepared by: authorized signatory single line diagram of 220/132/33 kv gss fatuha legend incomer 132kv harnaut 132kv gaighat line 132kv gaurichak line 132kv rly. 2 4 Construction of plinth for 5MVA,33/11KV Power Transformer with mounting No. Suppose there is a residential building block of 04 floors, total number of buildings - 6. Single Line Diagram of Power System Definition: Single line diagram is the representation of a power system using the simple symbol for each component. The Sub-transmission is at medium high voltage such as 33 kV, 11 kV AC. Under these services, we undertake protection and automation of all types of electrical substations. To explain this easier, we have divided the single line into three sections. 15) GOH S/S (EXISTING) Goh GSS (2x20)MVA 14 Km 33 KV Line 33 KV Lightning arrestor 33 KV fuse 33 KV Bus - bar 33 KV Bus isolator Terminal Gantry 33 KV L A. The design and construction of the transformers shall be subject to the approval of the Federal Electricity & Water Authority (FEWA). ii) 33 kV switching stations at sites other than those at Grid Supply Points and transmission substations. Single Line Diagram of 33/11 KV (1x3. 3 Apr 2014. Medium size power supply 11/0. The remainder of the one-line diagram reflects the low voltage system which is operated at 480V. 09mm (80mm2 aluminum area) and 6/4. It is coming again, the additional deposit that this site has.
