8. INTRODUCTION
Electrical Department plays a vital role in the Railway System.
. It is responsible for operation and maintenance of lighting
and ventilation in AC and Non-AC coaches in railways workshop
ajmer.
The Electrical Department has been divided into two wings:
-Electrical Services department
-Railway power house
-Diesel power station
- Train Lighting & Air-Conditioning (TL&AC).
9. Railway power house
• CONTENTS
➢ Equipment Used In Railway Power House Substations
1 Power Transformer
2 Distribution transformer
3 Instrument Transformer
4 Potential Transformer
5 Current Transformer
6 Circuit Breaker
7 Lightning Arresters
12. Lightning Arresters:-
• A surge arrester or
lightning arrester is a
device connected
between line and earth.
To discharge lightning
over voltages and
switching over voltages
to earth
13. Types of lightning arrester
Rod gap LA
Valve type LA
Horn type LA
Expulsion type LA
Multi gap LA
14. Wave trap
• To prevent high
frequency signals from
entering other zones.
16. Transformer
Transformer is a static device which
transfers electrical energy from one
electric circuit to another electric
circuit at constant frequency.
17. TYPES OF TRANSFORM ER
According to Construction:
a.Core type Transformer.
b.Shell Type Transformer.
According to the system of windings used in the Transformer.
a.Single phase T/R.
b.Three phase T/R
According to system of cooling to the Transformer.
a.ONAN (Oil Natural Air Natural)
b.OFAN (Oil Force Air Natural)
c.ONAF (Oil Natural Air Force)
d.OFAF (Oil Force Air Force)
• According to use
a.Power Transformers
i.Above 500 to 15000 K.V.A.
b.Distribution Transformers
i.From 5 to 500 K.V.A.
c.Instrument Transformers
i.Used with the measuring instruments
d.Auto Transformers
Used for low voltage circuits.
20. CURRENT TRANSFORMER
•
• Current transformer is used
for measurement of current
and as a protective device.
• It connect line to line in the
sub stations.
sec. turns > primary turns
• the ratio is given by
I1/I2 =N2/N1
22. CIRCUIT BREAKERS
• A circuit breaker is a
equipment which can
break a ckt
automatically under
fault conditions.
TYPES OF CIRCUIT
BREAKER
➢ Air blast ckt breaker
➢ Sf6 ckt breaker
➢ Minimum oil ckt
breaker
➢ Vaccum ckt breaker
23. DIESEL POWR STATION :-
Diesel Power station is the most important
part of Railway Power House. We can say
it, an energy power sources for railway,
when R.S.E.B. supply is failure due to any
reason.

26. TRAIN LIGHTING
•
On the basis of generation following train lightning system are
used :-
(EOG) End On Generation
1) Generating Voltage 415 V
2) Generating Voltage 450V
(MOG) Mid On Generation
(SGS) Self Generating System
1)24 V DC (from Alternator)
2) 110 V DC (Alternator)
27. End On Generation
• In this type of system electricity is generated by
power car.
• This system is used in trains having AC coaches
like Rajdhani express, Shatabdi express etc. Two
type of power cars are used
• 1) 415 V, 3 Phase AC
• 2) 750 V, 3 Phase AC
28.
29. Mid on generation
• This train lightning system is used on
small branch lines, hill area. In this
system power car is used in the middle
of all coaches therefore it is called as
Mid On Generator
30.
31. Self on generation
• In self generating coach electricity is generated in
coach by the generating equipment.
• In old T/L system dynamo was used but in
modified system brushless alternator are used
32.
33. Refrigeration and airconditioning
• Refrigeration
• Refrigeration is a
process in which work is
done to moving heat
from one location to
another.
• Air conditioning
• Air conditioning is the
removal of heat from
indoor air for thermal
comfort.
34.
35.
36. • R-134 is compatible with synthetic
oil. It is not much harmful to ozone
layer and safe according to global
warming.
37. Components of Refrigeration cycle
•
•
• Refrigeration cycle has four basic
components to work:
The evaporator unit
The expansion valve
The compressor
The condenser
