PROCEDURE FOR SHUTDOWN

                        PROCEDURE FOR SHUTDOWN 


                                           Step 1 :
Before shutting down, thoroughly study the circuits and identify which circuit breakers or control switches wants to open.  An alternative to the Consumer is to carefully study the supply mains, parallel feeders, duplicate busbar, etc.

                                          Step 2 :
 Keep the circuit breaker open and locked If you cannot lock the switch, remove the fuse and lock it and it should be kept secure.  Locking the circuit breaker and keeping the fuses secure will eliminate the possibility that the supplier may return the wrong supply unknowingly while working on the line.  Neutral links need to be disconnected.  In the event of some fault, the potential of the neutral is increased, so the neutral link must be split.  

                                         Step 3 :
Hang the "Man - at - work" notice board on the circuit breaker or switch handle, This causes the supplier to fail to turn the ON while working .  
           
                                        Step 4 :
Test the supply after checking to see if the tools used to run it are working correctly.  In case of an emergency shutdown, the wrong switch may be opened by inadvertence.  These mistakes can cause serious dangers when someone lands the circuit or works on the circuit.  The equipment used to measure the supply voltage must be made appropriate.  The equipment used to test the supply must be in good working condition.  Wear gloves for safety when testing the high tension line, You should also make sure that these rubber gloves are in good condition.

                                        Step 5 :
Equipment is required to earth.  Full security is guaranteed only if you shorten all lines and use proper earthing .  The earth conductor must be of sufficient size to withstand the entire current when the fault occurs.

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...
