THERMAL POWER PLANT
A thermal power station is a power plant in which the prime mover is
steam driven.
Water is heated, turns into steam and spins a steam turbine which
drives an electrical generator .
Electric power plants typically use three-phase or individual-phase
electrical generators to produce alternating current (AC) electric power
at a frequency of 50 Hz.

SUB-STATION
The place where power come first and distributed by steping up and
steping down.These are generally known as substation. Bhilai steel plant
substation may be classified in six part:-
1.MSDS-1
2.MSDS-2
3.MSDS-3
4.MSDS-4
5.MSDS-5
6.MSDS-6
![Page 8: Steel Plant](https://reader034.fdocuments.net/reader034/viewer/2022050713/547766e8b4af9f9e488b4577/html5/thumbnails/8.jpg)
MSDS 1 & MSDS 2 are main sub station and distribute the supply to
other MSDS.
These MSDS supply power to various small sub station in 11kv or 6.6kv
near big mills like Rail mill,merchant mills,rod mill etc.
In these mills step down the voltage for there required voltage.

Different Equipment of Switchyard:-
1. Lightning arrester
2. Isolator
3. Circuit breaker
4. Transformer
5 Current Transformer

Lightning Arrester
![Page 14: Steel Plant](https://reader034.fdocuments.net/reader034/viewer/2022050713/547766e8b4af9f9e488b4577/html5/thumbnails/14.jpg)
DEFINIATION:-
Lightning Arrestor is a device, which protects the
overhead lines & other electrical apparatus like transformer from over
head voltages & lighting.
Every instrument must be protected from the damage of lightning
strokes.
The three protections in sub stations are essential:
1. Protection for transmission line from direct strokes.
2. Protection of power station or substation from direct strokes.
3. Protection of electrical apparatus against traveling waves.

ISOLATOR:
![Page 16: Steel Plant](https://reader034.fdocuments.net/reader034/viewer/2022050713/547766e8b4af9f9e488b4577/html5/thumbnails/16.jpg)
DEFINIATION:-
A device which is used for protection of electrical
equipment from over voltage and over current.
Isolator for a 3-phase system must be operated all together.
One contact arm has a male contract while other has female contact.
Insulation supports contact arms.
Contacts are made or broken by motor operated mechanism.
When contact is to be opened then both arms are rotated in opposite
direction so that contact is broken.

CIRCUIT BREAKER(CB):
DEFINIATION:-
Automatic switching during normal or abnormal
conditions.
TYPES OF CB:
1. SF6 Circuit Breaker
2. Oil Circuit Breaker.
3. Air Blast Circuit Breaker
4. Vaccum Circuit Breaker
![Page 18: Steel Plant](https://reader034.fdocuments.net/reader034/viewer/2022050713/547766e8b4af9f9e488b4577/html5/thumbnails/18.jpg)
SF6 Circuit Breaker:
SF6 is not flammable and toxic
like oil.
It is easier to handle, maintain and
repair equipment fill with SF6.
SF6 has the property that
disassociated molecules recombine
rapidly after the sources of arcing is
removed when superior arching
occurs.
![Page 19: Steel Plant](https://reader034.fdocuments.net/reader034/viewer/2022050713/547766e8b4af9f9e488b4577/html5/thumbnails/19.jpg)
Oil Circuit Breaker
In bulk oil circuit breaker
transformer oil is used which
serves 2 purposes:
1. Media for extinguish arc as
well as for
2. Provide insulation between
current carrying parts and
metallic tank.
![Page 20: Steel Plant](https://reader034.fdocuments.net/reader034/viewer/2022050713/547766e8b4af9f9e488b4577/html5/thumbnails/20.jpg)
Air Blast Circuit Breaker:
In this type of circuit breaker compressed air is used as an arc
extinguishes medium.
In these circuit breakers arc is subjected to air blast axially or the arc.
The air blast cools the arc and sweeps away the arcing products to the
atmosphere.
This rapidly increases the dielectric strength of the medium between the
contacts and prevents the re- establishing the arc.
Consequently, the arc is extinguished and flow of current is interrupted.

Transformer:
DEFINIATION:-
Transformer
is an A.C. machine that transfers
electrical energy from one
electrical circuit to another.
![Page 22: Steel Plant](https://reader034.fdocuments.net/reader034/viewer/2022050713/547766e8b4af9f9e488b4577/html5/thumbnails/22.jpg)
Current Transformer
DEFINIATION:-
To step-down
currents for measurement,
control & protection this type of
transformer is called current
transformer(C.T)
