2. INTRODUCTION OF
GRID SUB-STATION
A sub station is a part of an electrical transmission,
and distribution system. Sub stations transform
voltage from high to low, or the reverse, or perform
any of several other important functions.

3. ●Sub-station should be located at load center
●Sufficient land area
●Grounding
●Easy of maintenance
●Possibility to Expand
●Reliability and Security

4. Transmission lines from this sub-
station

6. EQUIPEMENTS OF
SUB-STATION
●Lightning Arrester
●Wave Trap
●Isolator
●Instrument Transformers
●Power Transformer
●Insulator
●Circuit Breaker
●Bus Bar

7. LIGHTNING
ARRESTORS
To discharge
lightning over
voltages and
switching over
voltages to earth.

8. Wave Trap
To prevent
high frequency
signals from
entering other
zones.

9. ISOLATOR
Disconnection
under no-load
condition for
safety, isolation
and
maintenance.

10. CURRENT TRANSFORMER
To step-down
current for
measurement,
control &
protection.

11. POTENTIAL TRANSFORMER
The potential
transformer is
used to step
down voltage.
It is used to
measurement of
voltage.

12. TRANSFORMER
A transformer
is a static ac
device which
convert electric
energy from one
form to another.
Rating-220kv/
132KV,100MVA

13. INSULATOR
 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.

14. TYPES OF INSULATOR
Pin Type
Strain Type
Suspension Type

15. CIRCUIT BREAKER
Circuit breaker
are used for
switching and
protection.
Brake a circuit
and
automatically
under fault
condition.

16. TYPES OF C.B.
Minimum oil
Circuit Breaker.
 Air Blast Circuit
Breaker.
 SF6 Circuit
Breaker.
 Vacuum Circuit
Breaker.

17. BUS BAR
A busbar is a
metallic strip or
bar through
which a large no.
of feeders
operating at
same voltage
have to
connected.
