Task 3. Read the text and give the
title to it.
An electric cell
supplies electric energy provided its electrodes are of different materials. In
case the electrodes are of the same material they become charged but there is
no difference of potential across the terminals. Iron and zinc plates are commonly
used for producing negative electrodes since these materials produce a high
charge. Carbon is commonly used to produce positive electrodes.
The voltage output
of cells in use nowadays is from 1 to 2 V. The value of the output depends only
on the materials used for the electrodes. Besides, it depends on the
electrolyte of a cell. It does not depend on the size of a cell and its construction,
while the current capacity of a cell depends on the size of the electrodes.
The larger the size of the electrodes, the more current capacity they can
supply. When the size of the electrodes is increased the current capacity also
increases while the voltage output does not increase. Such is the relation
between the size of the electrodes and the current capacity.
Task 4. Answer the questions.
1. In what case does
a cell supply energy?
2. What materials are
commonly used for producing negative electrodes?
3. What does the
value of the output depend on?

Task 3. Read the text and give the
title to it.
A negative
transconductance oscillator consists of a pentode with the screen and suppressor
grids coupled together. The screen is more positive than the plate. The cathode
supplies electrons to both the screen and the plate. If the screen voltage
rises, this increase is transferred over to the suppressor. It becomes more
positive than before. A large quantity of electrons passes to the plate and a
small quantity of electrons passes to the screen. Thus, the screen current is
reduced. A negative resistance characteristic is produced in the screen circuit
at the terminals.
A tuned circuit is
connected to the terminals and in this way oscillations are produced.
Task 4. Answer the questions.
1. What is more
positive the screen or the plate?
2. In what way is the
screen current reduced?
3. What does negative
transconductance oscillator consist of?

A rheostat is a
resistor whose resistance value may be varied. Thus, a rheostat is a variable
resistor.
It is used to
change the resistance of circuits, and in this way to vary the value of current.
A rheostat
consists of a coil and a switch. Take into consideration that wire used for the
coil must have a very high resistance. When a rheostat is used its terminals
are connected in series with the load. The switch is used to change the length
of the wire through which the measured current passes. The resistance may be
changed to any value from zero to maximum.
The longer the
rheostat wire used in the circuit, the greater is the resistance.

A
high-capacity hydrogenerator produces an a.c. current at 22,000 V. The current
with the potential difference of 220,000 V is produced by means of the
transformers at a step-up station and then transmitted over the power lines. The
current potential difference is lowered to medium 6,600 V at the main step-down
substation at the end of the line. From here the power is transmitted to the
next substations. Transformers stepping the voltage down from 6,600 V are
installed at those substations. Due to voltage conversion, alternating current
is used widely in industry. Direct current for battery charging for trams,
trolleybuses and electric locomotives is changed from alternating current by
means of rectifiers.
Task 4. Answer the questions.
1.
Where
is the current potential difference lowered?
2.
Where
is the main step-down substation installed?

In the electric
generating field, as well as in the electric-transmission and
storage-technology areas, considerable attention is focused on the use of
superconductivity conductors. Cooling an electric conductor to temperatures close
to absolute zero (-273o C) results in the conductors’ losing their
resistance to electric current. Accordingly, their ohmic losses also drop
greatly. Current densities of tens of millions amperes per sq cm can be
tolerated in such conductors. Cryogenic technology being now mastered, one can
foresee the possibility of supercooling not only generators but also
underground transmission lines and storage coils.
Task 4. Are the statements true or
false?
1. Conductors can
never lose their resistance to the flow of electric current.
2. Generators and
underground transmission lines can be supercooled.

Transmission
lines in which compressed gas is used as insulator have a number of advantages.
The main advantages are simplicity of construction and low cost. What is the
construction of compressed-gas-insulated transmission lines? It is rather
simple. They comprise a number of phase conductors; each phase conductor is
placed inside a tube and centered by means of circular spacers. The tube space
is filled with compressed gas - usually sulphur hexafluoride. Each tube in a
345-kV line has a diameter about 50 cm. The system including
compressed-gas-insulated transmission has the following advantages: its losses
are rather low, they are considerably lower than those of cable transmission.
Unlike cables, compressed-gas- insulated transmission system can be designed
for ultra-high frequencies. No external electric field appears in the system.
The shunt capacitance is considerably less for a gas-insulated line than for a
cable. A gas-insulated line can thus transmit power over larger distances than
cable lines. The system should be protected against metallic particles. In case
metallic particles get into the system, they cause a fault - a dielectric
breakdown.
Task 4. Answer the questions.
1. Does the system
described have any advantages? What are they?
2. What gas is the
space filled with?
3. Why should the
system be protected?

The
Sun radiates to our planet great amounts of energy. This energy input fuels all
our biological processes and is the original source for hydropower, wind power,
and fossil fuel resources. Environmentally; and economically, the Sun is our
greatest energy source. Why then is the direct use of solar energy so limited
for industrial, domestic, commercial, and transportation purposes? First, solar
energy arrives in small quantities - only about one kW; per square meter;
second, it does not arrive at all during night hours. Third, it is very
difficult to transform it into useful energy forms except j low-grade heat.

Dynamo is a common
device for converting mechanical energy into electric energy. This process
depends on the fact that if an electrical conductor moves across a magnetic
field, an electric current flows in the conductor.
Usually a dynamo
includes an electromagnet, called the field magnet, between the poles of which
a suitable conductor, usually in the form of a coil, called the armature, is
rotated. The mechanical energy of the rotation, in the form of a current in the
armature, is thus converted into electric energy.

A high tension
transmission line leading from one city to another makes a guideway for
aviators during the day time, since it is visible from great distances.
However, at night the high tension transmission line becomes a danger for the aviator,
rather than a help.
In order to assist
the aviator in locating the transmission line, a signal marking its position is
provided; this signal is a luminous lamp attached to the conductors of the
transmission line; the lamp is lighted by the potential on the line and serves
to indicate its position. This signal also makes a safety device. If the line
is under tension, the attending personnel working on it will know that
potential is on the line.
A glass tube
filled with neon gas was found to be suitable for this kind of work. Instead of
a neon lamp, in some cases, a low current filament lamp may also be used as a signaling
source.

Large
steam-turbine plants have two forms: condensing plants or electric power
plants.
The great masses
of hot steam, having accomplished the mechanical work in the tribunes of
condensing steam-turbine plants, are condensed, i.e. are cooled down and turned
back into distilled water, and returned to the boiler for production of steam
to activate the turbine.
Condensation of
steam takes place in condenses where the hot steam is cooled when it comes in
contact with tubes through which cold water, supplied from a water reservoir
(river or lake), is circulated. This cooling water, after it takes the heat
from the spent steam, is returned to the water source carrying along with it
the unutilized heat energy. This water is called the circulating water. The
importance of the distilled water for feeding steam boilers is extremely great
since chemically clean water decreases the formation of scale in the boiler
tubes, and, thus, makes their service life longer.
The electric power
generated in such plants is transmitted over long distances for the supply of
large industrial regions. So these plants are called regional thermal power
plants. Heat and electric power plants, in addition to electric power
generation, also supply heat to closely located consumers (within a radius of
50 km), i.e. serve as district heat plants. To such heat consumers belong all
kinds of industrial enterprises that require heat for production purposes, and
also municipal consumers such as baths, laundries and the heating systems of dwelling
houses and other buildings.

It is of great
importance, therefore, to make regular tests of insulation resistance of all
machinery so as to detect possible faults. Different conditions may influence
the value of the insulation resistance.
It is advisable,
therefore, to make the test of the machine as soon after it has been shut down
as possible, when the insulation resistance is likely to be lowest. If, after
the motor has just been shut down, the insulation resistance is found to be
satisfactory, it may be assumed that it will be better at any other time
provided that the machine does not stand idle for long in a humid atmosphere.
Faults on
electrical machinery must be due to one of two causes. One is the absence of
continuity in the conductor which is supposed to be carrying the current. The
other is the absence, or partial absence, of insulation. The latter is by far
the more common and the more dangerous of the two. A burnt out armature, for
example, is usually due to insulation failure.
A drop in
insulation resistance may often be accounted for, for example, by damp weather.
As regards the
effect of temperature it should be noted that the insulation resistance of
motors and generators is generally lower when they are hot than when they are
cold as the insulating varnishes used in the building of the machines have a
lower resistance when hot than when cold.

Electric power is
generated by converting heat, light, chemical energy, or mechanical energy to
electrical energy. Most electrical energy is produced in large power stations
by the convirsion of mechanical energy or heat. The mechanical energy of
falling water is used to drive turbine generators in hydroelectric stations,
and the heat derived by burning coal, oil, or other fossil fuels is used to
operate steam turbines or internal-combustion engines tat drive electric
generators. Also, the heat from the fissioning of uranium or plutonium is used
to generate steam for the turbine generator in a nuclear power plant.
Electricity
generated by the conversion of light or chemical energy is used mainlyfor
portable power sorces. For example, a photoelectric cell converts the energy
from light to electrical energy for operating the exposure meter in a camera,
and a lead-acid battery converts chemical enervgy to electrical energy for
starting an automobile engine.
Electricity power
produced in large power stations generally is transmitted by using an
alternating current that reverses direction 25, 50, or 60 times per second. The
basic unit for measuring electric power is the watt – the rate at which work is
being done in an electric circuit in which the current is one ampere and the
electromotive force is one volt.
Ratings for power
plants are expressed in kilowatts (1000 watts) or megawatts (1 millin watts.
Electric energy consumption normally is given in kilowatts-hours – that is, the
n umber of kilowatts used times the number of hours of use.

On November 9, 1965,
at 5:16 p.m., a back-up relay failed at one of the five main transmission lines
at № 2 station near Toronto, Canada. As the load had shifted to the other four
lines, they became overloaded, and as a result the relays failed in all four
lines. The plants got overloaded, which caused them to shut down. Within
minutes, power plants in Canada, New York, and the New England states got out
of service. The blackout affected 30 million people and covered an area of
306 000 sq. m. in some areas such as New York City power was not restored
for about 13 hours.
This massive power
blackout resulted in the construction of the national Electric Reliability
Council in June 1958. This council sets standards for the design, operation and
maintenance of generating and transmission systems. These standards serve to
prevent a failure in one power system from spreading to other systems. Yet local
system failures cannot be avoided.
Nowadays in some
European countries and in the US there are from 60 to 80 power interruptions
per year, in which there is a loss of service for customers for more than 15
minutes. Mostly these interruptions are caused by weather conditions – ice,
freezing snow, lighting or storms. There can be also failures of equipment –
transformers, relays, insulators and so on. However, the reliability of
electric service is extremely high.
Task 4. Answer the questions.

The two main types
of power plants traditionally have been the fossil-fuel steam-electric plant
and the hydroelectric plant. Other types, including internal-combustion-engine
plants and nuclear plants also have been built. The selection of a particular
type of generating plant and its location involves consideration of a number of
factors such as plant, fuel, and transmission line costs; availability of
cooling water; and environmental considerations.
For several
reasons, the relative importance of the various types of power plants has been
shifting. Good sites for new hydroelectric plants have become scarce in many countries.
Distribution networks have been extended so that less expensive power from large
steam-electric plants because the cost of coal and oil has been increasing.
In the United
States in 1970, fossil-fuel steam-electric plants for 16%, and nuclear plants
2%.
In 2000 45 % of
the electric power in the United States is generated from fossil-fuel
steam-electric plants, 45% from nuclear plants, and 10% from hydroelectric
plants.

The accident, which was of global
concern was the accident in Ukraine in the Chernobyl power plant located in
Polesye on the River Pripyat.
On 26 April, 1986,
Unit 4 of the Chernobyl nuclear plant suffered a major accident. The installed
electrical generating capacity was 1 GW. The accident followed some engineering
tests of a generator.
During the tests,
basic operating safety rules were being violated. Most control rods were
withdrawn from the core and the safety systems were switched off. Two
explosions and a fire that followed them damaged the reactor and the
containment building. The graphite started to burn. Explosive energy was
released, which resulted in the 1000 ton cover plate of the reactor being
lifted up.
A prolonged
release of large quantities of radioactive products transported by the cloud
from Chernobyl was detected not only in northern and southern Europe but also
in Canada, Japan and the USA.
The major part of
the release took place over the period of about ten days. There were two peaks
in release rate (26th April and 5th May). Later on, the
release continued for many weeks at a lower rate before the destroyed reactor
was finally sealed, which took place some five months later.
Initially the
cloud of radioactive material was carried over the Baltic Sea into Scandinavia.
After a few days the wind direction rotated clockwise and the cloud travelled
eastwards across the USSR and southwards to Turkey.
The total mass of
the radioactive particles released in the accident was about 6000-8000 Kg. More
than half of it was deposited near the plant but the rest travelled thousands
of kilometers.
The accident in
Chernobyl nuclear plant has shown that large-scale accidents in nuclear power
plant can lead to contamination of the entire continent.
Task
