The project is designed to control the speed of a single phase induction motor in three steps by using cyclo convertor technique by thyristors. A.C. motors have the great advantages of being relatively inexpensive and very reliable.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

6. Diesel fuel
The word "diesel" is derived from the German inventor Rudolf
Christian Karl Diesel who in 1892 invented the diesel engine.
Diesel, or diesel fuel, is any fuel that is used to operate a diesel
engine.
Most commonly, it refers to a specific liquid fuel obtained by the
fractional distillation of petroleum, often called petro diesel.
Alternative diesel fuels not derived from petroleum are biodiesel
and biomass to liquid (BTL) or gas to liquid (GTL) diesel.
Diesel and petrol both are petroleum product. Yet diesel is more
used.
7. Locomotive
A locomotive is a railway vehicle that provides the motive
power for a train.
The word originates from the latin loco – "from a place" +
Medieval Latin motivus, "causing motion", and is a shortened
form of the term locomotive engine.
The first successful locomotives were built by Cornish
inventor Richard Trevithick.
Locomotive in India consist of electric and
diesel locomotives .Steam locomotives are no
longer used, except in heritage area.
Locomotives are also called locos or engines.

My four week training was confined
to three different sections
EMS
10. Main Receiving Substation(MRS)
• MRS receives main supply from UPPCL at 33kv. Earlier it was
UPSEB.
• This is step down with 7.5MVA transformer. The 33kv feeder is
transformed is two 11kv feeder with a bus coupler in
between.
• The MRS follows the ring type distribution system for
supplying power to DLW. The advantage of ring type system is
that each substation is fed from two sides. If in case one line is
faulted then the substation is fed by other line. But major
disadvantage of ring type system is that it is too costly.

18. RELAYS :
Relays are used for protection of the power system from
different faults which are occurring in the power system. A
relay is a simple electrochemical switch made up of an
electromagnets and a set of contacts. Relays are found
hidden in all sorts of devices.
TWO TYPE OF RELAY USED IN MRS :-
(QUANTITY AND AMPLITUDE)
Definite relay
Inverse relay
19. CAPACITOR BANK:-
In the electrical system the power factor play a important role because by
improving the power factor one can reduce losses . Generally power factor
should not be brought below 0.8 for industrial loads. To improve power
factor, capacitor bank are placed in parallel with the power supply. In
DLW, 600KVAR capacitor bank is used for the improvement of power factor.
Reason for Improvement of Power Factor:
Reduced losses
Reactive power decreased active power increases
Efficiency of machine increases
Advantages of Using Capacitor Bank:
Easy to increase the capacity
Reliability of the system is high
Controlling of bank is easy
Maintenance is easy

In this case of maintenance, repair can be done after the break down occur.
Breakdown of machine can occur due to unpredicted failure of components
which cannot be prevented or due to gradual wear and tear of the part.
PREVENTIVE MAINTENANCE
In this case maintenance is done on the basis of predication checking.
This is sometimes called “maintenance maintenance “ or “systematic point
maintenance”. It is an extremely important function for the reduction of
maintenance cost, less expenditure of repairs etc.
• Reduction in production downtime.
• Lesser over-time pay for maintenance personnel.
• Lesser number of standby equipments in needed.
