INTRODUCTIONIn 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

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.

INCOMING FEEDER: 220KV PURANA GHAT LINE-1.

220KV PURANA GHAT LINE-2.

220KV BASSI LINE.

CONCLUSION.

LIGHTNING ARRESTORLightning 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.

INSULATERAn 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.

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

CURRENT TRANSFORMERThe current

transformer are used to stepped down .

It is used to measurement/control/protection.

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.

BUSBARSBus 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.

PROTECTIVE REALAYA 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.

CONTROL PANEL

CONTROL PANELColor coding:-

1. 33kv (Green)

2. 132kv (black)

3. 220kv (Broun)

4. 440kv (indigo)

5. 110kv (orange)

POTENTIAL TRANSFORMERThe potential transformer is used to one

electrical form to another form .It is used to measurment of current &voltage.

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.
