This document provides an overview of turbo generators. It describes their history, working principle, design process, manufacturing of rotor windings, applications, advantages, and disadvantages. Turbo generators are large machines that directly connect turbines to electrical generators in order to generate power. They can be powered by steam, gas, or water turbines. The document outlines the 12 step design process and discusses the construction and components of rotor windings. Turbo generators provide reliable, economic, and renewable energy but require high maintenance costs. Future research focuses on improving insulation testing techniques.

3. INTRODUCTION
.
Turbo generator is a turbine directly connected to electrical
generators for the generation of electric power. These
machines are the largest
energy converters found in the
world. They can also be used as auxiliary power units. They
are of 3 types namely:
1)Steam turbine generators
2)Gas turbine generators
3)Hydro turbine generators

4. HISTORY
 The
turbo generator is invented
by Blathy Otto a electrical engineer
of Hungary ,central Europe in the
year 1912.
Later it was developed by Michael
Faraday a British scientist by using a
theory
of
Induction”
“Electro
Magnetic

5. WORKING PRINCIPLE
An emf is induced in a
conductor when it is cut by
magnetic flux is known as
electromagnetic induction.

6. STEP BY DESIGNING PROCESS OF
TURBO GENERATOR
There are 12 designing
steps to construct the
turbo generator they are:
1)Press shop
2)Light machine shop
3)Heavy machine shop
4)Copper shop

7. 5)Coil shop
6)Insulation shop
7)Rotor windings
8)Stator windings
9)Balancing
10)VPI plant
11)Assembly
12)Testing

8. MANUFACTURING OF ROTOR WINDINGS
The rotor in turbo generators is the magnetic field. this are of
2 types:
1)Solid rotor
2)Laminated rotor.
•THE MAIN PARTS OF ROTOR
1)Rotor shaft
2)Rotor Slot wedges
3)Damper holes
4)Rotor retaining rings
5)Fans

9. •CONSTRUCTION OF ROTOR WINDINGS

11. APPLICATIONS OF TURBO GENERATORS
1. Gas Turbines drive the smallest class of turbogenerators. The motive force for these turbines is
the burning of gaseous fuels. Because they can be
started and stopped easily, they are used for a
variety of intermittent applications including
emergency power
2. Steam Turbines drive much bigger turbogenerators. The steam is generated by a variety of
methods including burning coal, nuclear power
and geothermal energy. These types of turbogenerators supply the bulk of the electrical power
in the US and other countries.

12. 3. The third class of Turbo-generator are powered
by water turbines. Invented in the 19th century
water turbines are very efficient devices for
extracting energy for moving water. They are used
in virtually all hydro-electric power plants world
wide.

13. ADVANTAGES OF TURBO GENERATORS
Turbo generator concept is simple and
time testing.
It can be generated from the renewable
energy sources which are environmental
friendly.
The life span of the machine is long.
Economic in cost compare to other
generators, hence in US 90% of electrical
generation is done by turbo generators.

14. DIS- ADVANTAGES OF TURBO
GENERATORS
As the turbo generator is high voltage
machine
the possibility of causing a spark in air and the
danger of electric shock by contact may occur.
 Repairing cost is high.
Maintenance cost is high

15. CONCLUSION
As turbo generators are high voltage machines
which are ranging from less than1500volts,hence
the
machine
efficiency
is
accurate.
Turbo
generators are also more reliable in nature. As the
production of sources are taken from the non-
renewable energy sources the cost is economic.

16. FUTURE SCOPE
The scientists are investigating the technical and logistical
merit of performing offline quadratic rate partial discharges
test on the stator winding insulation besides VPI technique of
turbo generators. A series of laboratory based
insulation
research studies on stator bars have been conducted to
gain a better understanding of the various parts discharge
phenomenon involved.
