RING MAIN BUSBAR

        RING MAIN BUSBAR:



                                               fig.1.1

           Fig.1.1 shows the arrangement of ring bus bar system. The ends of the bus bars are returned to form a ring. In this system each feeder is supplied from two paths. By a dopting this scheme of connections, the alternators connected to any one of the bus bar section can be used for supplying the load to the feeders on any section.


ADVANTAGES :
                          1. Each feeder is supplied from two paths. 
                          2. The arrangement is quite economical

DISADVANTAGES :
                          1.  The opening of any section of the breaker may cause overloading of the circuits.
                          2. It is difficult to add any new cirouit to the ring

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...
