TRANSFORMER
A transformer is an electrical device that transfers
energy between two or more circuits through
electromagnetic induction.
A varying current in the transformer's primary winding
creates a varying magnetic flux in the core and a
varying magnetic field impinging on the secondary
winding. This varying magnetic field at the secondary
induces a varying electromotive force (EMF) or voltage
in the secondary winding. Making use of Faraday's Law
in conjunction with high magnetic permeability core
properties, transformers can thus be designed to
efficiently change AC voltages from one voltage level to
another within power networks
Transformers range in size from RF transformers less
than a cubic centimeter in volume to units
interconnecting the power grid weighing hundreds of
tons. A wide range of transformer designs is
encountered in electronic and electric power
applications. Since the invention in 1885 of the first
constant potential transformer, transformers have
become essential for the AC transmission, distribution,
and utilization of electrical energy
TYPES OF TRANSFORMERS
Various specific electrical application designs require a
variety of transformer types. Although they all share
the basic characteristic transformer principles, they are
customizing in construction or electrical properties for
certain installation requirements or circuit conditions.
Autotransformer: - Transformer in which part of the
winding is common to both primary and secondary
circuits.
Capacitor voltage transformer: - Transformer in
which capacitor divider is used to reduce high voltage
before application to the primary winding.
Distribution transformer, power transformer: International standards make a distinction in terms of
distribution transformers being used to distribute
energy from transmission lines and networks for local
consumption and power transformers being used to
transfer electric energy between the generator and
distribution primary circuits.
Phase angle regulating transformer: - A specialized
transformer used to control the flow of real power on
three-phase electricity transmission networks.
Scott-T transformer: - Transformer used for phase
transformation from three-phase to two-phase and vice
versa.
Poly phase transformer: - Any transformer with more
than one phase.
Grounding transformer:- Transformer used for
grounding three-phase circuits to create a neutral in a
three-wire system, using a wye-delta transformer, or
more commonly, a zigzag grounding winding.
Leakage transformer:- Transformer that has loosely
coupled windings.
Resonant transformer:- Transformer that uses
resonance to generate a high secondary voltage.
Audio transformer:- Transformer used in audio
equipment.
Output transformer:- Transformer used to match the
output of a valve amplifier to its load.
Instrument transformer:- Potential or current
transformer used to accurately and safely represent
voltage, current or phase position of high voltage or
high power circuits.
APPLICATIONS
Transformers are used to increase voltage before
transmitting electrical energy over long distances
through wires. Wires have resistance which loses
energy through joule heating at a rate corresponding to
square of the current. By transforming power to a
higher voltage transformers enable economical
transmission of power and distribution. Consequently,
transformers have shaped the electricity supply
industry, permitting generation to be located remotely
from points of demand. All but a tiny fraction of the
world's electrical power has passed through a series of
transformers by the time it reaches the consumer.
Transformers are also used extensively in electronic
products to step-down the supply voltage to a level
suitable for the low voltage circuits they contain. The
transformer also electrically isolates the end user from
contact with the supply voltage.
Signal and audio transformers are used to couple
stages of amplifiers and to match devices such as
microphones and record players to the input of
amplifiers. Audio transformers allowed telephone
circuits to carry on a two-way conversation over a
single pair of wires. A balun transformer converts a
signal that is referenced to ground to a signal that has
balanced voltages to ground, such as between external
cables and internal circuits.

TRACTION MOTORS
A traction motor is an electric motor used for propulsion
of a vehicle, such as an electric locomotive or electric
roadway vehicle.
Traction motors are used in electrically powered rail
vehicles such as electric multiple units and other
electric vehicles such as electric milk floats, elevators,
conveyors, and trolleybuses, as well as vehicles with
electrical transmission systems such as diesel-electric,
electric hybrid vehicles and battery electric vehicles.
Traction motor is also a term that has been used as a
more general category for high reliability and high
performance motors.
Motor types and control
Direct-current motors with series field windings were
the oldest type of traction motors. These provided a
speed-torque characteristic useful for propulsion,
providing high torque at lower speeds for acceleration
of the vehicle, and declining torque as speed increased.
By arranging the field winding with multiple taps, the
speed characteristic could be varied, allowing relatively
smooth operator control of acceleration. A further
measure of control was provided by using pairs of
motors on a vehicle; for slow operation or heavy loads,
two motors could be run in series off the direct current
supply. Where higher speed was desired, the motors
could be operated in parallel, making a higher voltage
available at each and so allowing higher speeds. Parts
of a rail system might use different voltages, with
higher voltages in long runs between stations and lower
voltage near stations where slower operation would be
useful.
A variant of the DC system was the AC operated series
motor, which is essentially the same device but
operated on alternating current. Since both the
armature and field current reverse at the same time,
the behavior of the motor is similar to that when
energized with direct current. To achieve better
operating conditions, AC railways were often supplied
with current at a lower frequency than the commercial
supply used for general lighting and power; special
traction current power stations were used, or rotary
converters used to convert 50 or 60 Hz commercial
power to the 16 2/3 Hz frequency used for AC traction
motors. The AC system allowed efficient distribution of
power down the length of a rail line, and also permitted
speed control with switchgear on the vehicle.
AC induction motors and synchronous motors are
simple and low maintenance, but are awkward to apply
for traction motors because of their fixed speed
characteristic. An AC induction motor only generates
useful amounts of power over a narrow speed range
determined by its construction and the frequency of the
AC power supply. The advent of power semiconductors
has made it possible to fit a variable frequency drive on
a locomotive; this allows a wide range of speeds, AC
power transmission, and rugged induction motors
without wearing parts like brushes and commutators.
