1. 220 KV GRID SUB STATION IG NAGAR JAIPUR :-
SUBMITTED TO:- SUBMITTED BY:-

JAIPUR
RAJASTHAN TECHNICAL UNIVERSITY, KOTA

2. In India Electrecal power is Generated at a voltage
of 11kv to 33kv ,which is taken stepped up to the
transmission level in the range of 66kv to 400kv
member of transmission and switching have to be
created these are known as ”Substation”.
Substation is an assembly of apparatus ,which
transform the characteristics of electrical energy
from one form to another say from one voltage
level to another level. hence a substation is an
Intermedate link between the Genrating station
and consumer

Substations have switching, protection and control equipment and one
or more transformers. In a large substation, circuit breaker are used to
interrupt any short-circuits or overload currents that may occur on the
network

4. 220KV INDRA GANDHI NAGAR
GRID SUBSTATION
220kv IGN s/s is a convensional, hybrid substaion.
It is part of transmission system.
33kv substation is gas insulated substation which is
inside the control room.
 for communication purpose PLCC is used.

5. INCOMING FEEDER:
 220KV PURANA GHAT LINE-1.

8. LIGHTNING ARRESTOR
 Lightning arrestor provide protection to all the
equipment against the HV.an electric discharge
between cloud and earth ,between cloud and
charge enters of some loud is known as lightning.
 It is provide to safety transmission &distribution
line.

9. INSULATER
An electrical insulator is
a material whose
internal electric charge
do not flow freely and
therefor make it very
hard to conduct an
electric current under
the influence of an
electric field.

10. POWER TRANSFORMER
•For stepping up or down the system voltage, power transformers are used in
the substations. At generating end, the voltage is only stepped up for
transmission of power while at all the subsequent substations the voltage is
gradually stepped down to reach finally to working voltage level

11. CURRENT TRANSFORMER
The current
transformer are used to
stepped down .
It is used to
measurement/control/
protection.

12. CIRCUIT BREAKER
 Circuit breaker are used for
switching and protection.
 Brake a circuit and
automatically under fault
condition.
 A circuit breaker consist of
fixed and moving contact
called electrode under
normal condition.

13. BUSBARS
 Bus bars are common
electrical component
through which a
large no. of feeders
operating at some
voltage have to
connected.
 It is used to connect
to transmission line
which go to
electricity.
 It is used to high
material conductor.

14. PROTECTIVE REALAY
 A Protective relay is a
device which detect
the fault.
 It is to detect after
their go to command
circuit breaker
 It is provide to safety
in electrical
equipments.

15. CONTROL PANEL

16. CONTROL PANEL
 Color coding:-
1. 33kv (Green)
2. 132kv (black)
3. 220kv (Broun)
4. 440kv (indigo)
5. 110kv (orange)

17. POTENTIAL TRANSFORMER
The potential transformer is used to one electrical
form to another form .
It is used to measurment of current &voltage.

18. WAVE TRAP:-

19. SINGLE LINE DIAGRAM:-

20. CONCLUSION
 An Engineer need to have not just theoretical but
practical as well as and so every student is supposed to
undergo a practical training .session after 3rd year
where I have impaired the knowledge about
transmission ,distribution .during the 45 days training
session. we have acquainted with the repairing of a
transformer and testing of transformer. At last is
would like to say that practical training taken at 220kv
gss ig nagar has broadened my knowledge and
widened my thinking as a professional.
