4. INTRODUCTION
• It is the fourth largest railway network in the world by
size,with 1,21,407 km of total track with 7,349 railway
stations till now .
• In indian railway 49% of routes are electrified with
with 25 kv Ac electric traction .
• The power consumption of indian railway is around
2.5% of the country’s total electricity consumption

5. SUBSTATION
•A substation is a part of an electrical generation, transmission, and
distribution system.
• Substations transform voltage from high to low, or the reverse, or
perform any of several other important functions.

6. •Lighting arrester provide protection to all
equipment against the high voltage.
•They are connected between
the line & ground at the substation &
always parallel with the equipment to
be protected.
LIGHTING ARRESTER

7. CIRCUIT BREAKER
 The function of circuit breaker is to provide opening and closing
the current carrying contacts.
 Electrical circuit breaker is a switching device which can be
operated manually as well as automatically for controlling and
protection of electrical power system respectively.

8. CURRENT TRANSFORMER
 current transformer is used for measurement of alternating
electric current.
 It is used to moniter high current or current at high voltage.
 It used monitoring the operation of smartgrid .

9. POTENTIAL TRANSFORMER
 Potential transformers have a large no. of primary turns & a
few no. of secondary turns.
 Potential transformers are used in electrical power system for
control the system voltage to safe value .

10. RELAY
 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.

11. INSULATOR
 An electrical insulator is a material
whose internal electric charge do not
flow freely & therefore the current will
not flow from it .
 In railway use two type insulator
1) Pin type insulator
2) Suspension type insulator

12. EARTHING
 In electricity supply systems, an earthing system is circuitry
which connects parts of the electric circuit with the ground, thus
defining the electric potential of the conductors relative to the
Earth’s conductive surface.

13. REACTOR
 Reactors are used in the
power system network for
current limiting and for
compensation of reactive
power.
 There are two type of
reactor
1) Series reactor- connected
in series for current
limiting.
2) Shunt reactor- connected
in shunt for compensation
of reactor power.

14. DO FUSE
 Used to protect transformers
on rural distribution network.
 It is also particularly useful for
inaccessible substation where
induction of fusing is of
advantage

15. POWER HOUSE SUPPLY
 The two supplies of 11kv taken from receiving substation
used two OCB.
 OCB 1 – buster chambal & gudla.
 OCB 2 – DRM office.
 OCB is connected to the 400kva transformer that change
11kv to 440kv.

16. CONTROL
PANEL

17. GENERATOR
 A generator is a device that
converts motive
power into electrical power for
use in a external circuit.
 There are two types of
generator –
1. Self starting generator.
2. Vaccum type generator.

18.  There is the separate sub-station to power supplying for DRM
office.
At the this substation 11kv supply comes from power house sub
station.
 That is divided into two parts, both lines passing through
switches & then goes to two transformer,both transformer are
delta-star connected, rating of one transformer is 250KVA.
DRM OFFICE SUB-STATION SUPPLY

19. RAILWAY PLATFORM LIGHTING SYSTEM
 All the railway platform large amount of power required for
different types of electric equipment for saving power at the
station sensor technique are used.
 There are two types of sensor are used:
1) Light sensor
2)Train scheduler sensor

20. ENERGY CONSERVATION TECHNIQUE
1) At the railway station 40, 60 & 100W bulbs are Replaced
by 20, 11, 15W CFL this also use for domestic purpose.
2) Solar panel lighting system are used at the streets and the top
of the platform .
3) AC ceiling fan of 90, 60W are change by 45W fan .
