bus bar

                                          BUS BAR

            Bus bar is a group of conductor, which is used to carry the current from one place to another place. in bus bar, material like bronze, aluminium, copper are used as a bus bar. aluminium is good to use, because it is cheap, less in weight. The bus bar's are manufacture in the shape of rectangle, square, and round tubes. The most common of the bus-bars are 40x4mm (160 mm); 40x5 mm (200 mm2); 50x6 mm (300mm2); 60x8 mm (480 mm2) ; 80x8 (640 mm2) and 100x10 mm (1000 mm).


WHY BUS BAR'S ARE USED IN ELECTRICAL SYSTEM:

             In some case using of bus bar's are most useful then the using of cables

EXAMPLE:  in a power plant or power distribution center, sometimes they handles high amount of power, for that cables aren't convenient. they might need a cable as thick as a firehose and six times as heavy to carry the current. If not cable can melt, In those cases, instead of using cable, we can just use slabs of metal instead.

ADVANTAGES OF BUS BAR :

       *  Bus bars reduce system cost 
       *  Improve reliability
       *  Increase capacitance
       *  Eliminate wiring errors
       *  They also lower inductance and increase                                   capacitance.  
       *  The physical structure of bus bar offers unique                       features in mechanical design.

DISADVANTAGES OF BUS BAR :

  • Commercially not viable if the number of switch gears is low
  • Specialists needed for construction of the busbar system from a wiring diagram
  • Lack of adapters for mounting different electrical devices on the busbar
  • Special type of busbars needed to construct busbar system which can carry current more than 800 Ampear

LAYOUT OF 110/11KV SUBSTATION

                   LAYOUT OF 110/11KV SUBSTATION: CIRCUIT DIAGRAM: THEORY : 1. The 3 phase 3 wire 110 KV feeder is tapped and brought to the Gang operated (GO) switch. The GO switch consists of isolators connected in each phase of the 3 phase line. 2. From the isolator the 110KV line is brought to the 110 KV Bus bar through Circuit Breaker (CB).  3. From the 110KV Bus bar, the 110 KV line is fed to the HT side of the 110KV/11KV stepdown transformer through Isolator. The transformer steps down the voltage to 11KV.  4. In fig.1.2. two 110/11KV transformers are connected from the 110 KV bus bar and the LT side of the power transformers are connected to the common 11KV Bus  through CB and Isolators. 5. From the 11KV Bus bar no of feeders are taken through  isolator and CB.  6. Lighting arresters are provided for protection from lightning and current transformers for...

single bus bar and single busbar with sectionalisation

                                            BUS BAR 1.                               SINGLE BUS BAR                 In this way, only one set bus - bar is attached to the entire generating station.  All transformers, generators and feeders are connected to this single bus - bar.  Generators are connected to the bus - bar via isolator and circuit breakers.  Similarly to incoming and outgoing feeders via isolator and circuit breakers are attached with bus bar. This system will suitable for both A.C and D.C ADVANTAGES:                         1.  Only one circuit breaker is required for each                ...

ELECTRICAL TRACTION

                              ELECTRICAL TRACTION : ELECTRIC TRACTION :            Electric traction means a locomotion in which the driving force is derived from electric motors.  There are many advantages of electric traction over other forms of jocomotion in the current days of traction in any country of development.  In fact, it is a fast-paced, safest and economical way of transporting and transporting goods to the modern day. In this type of drive the locomotive is equiped with a d.c series motor or ac series motor or three phase induction motor. The electric energy is directly fed into the motor and torque developed by the propelling the train.                             TRACTION SYSTEMS : The most commonly used traction methods are as follows. 1.  Steam engine drive...
