220 KV GRID SUB STATION IG NAGAR JAIPUR :-
SUBMITTED TO:- SUBMITTED BY:-
Miss. VICKY JAIN SURENDRA KUMAR MEENA
SINE INTERNATIONAL INSTITUTE OF TECHNOLOGY,
RAJASTHAN TECHNICAL UNIVERSITY, KOTA
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
Fig.1 – 220 KV GSS ,IG NAGAR JAIPUR
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
220KV INDRA GANDHI NAGAR
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.

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
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
•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
transformer are used to

Circuit breaker are used for
switching and protection.

A circuit breaker consist of

It is to detect after
their go to command
It is provide to safety
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.
