Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

3. INTRODUCTION
A transformer is a device that changes ac electric power at one
voltage level to ac electric power at another voltage level
through the action of a magnetic field.
There are two or more stationary electric circuits that are
coupled magnetically.
It involves interchange of electric energy between two or more
electric systems
Transformers provide much needed capability of changing the
voltage and current levels easily.
They are used to step-up generator voltage to an appropriate
voltage level for power transfer.
Stepping down the transmission voltage at various levels for
distribution and power utilization.
4. WHAT IS TRANSFORMER
A transformer is a static piece of apparatus by means of
which an electrical power is transferred from one
alternating current circuit to another electrical circuit
There is no electrical contact between them
The desire change in voltage or current without any
change in frequency
Symbolically the transformer denoted as
NOTE :
It works on the principle of mutual induction
5.
6. STRUCTURE OF TRANSFORMER
The transformer two inductive coils ,these are electrical
separated but linked through a common magnetic current
circuit
These two coils have a high mutual induction
One of the two coils is connected of alternating voltage .this
coil in which electrical energy is fed with the help of source
called primary winding (P) shown in fig.
The other winding is connected to a load the electrical energy
is transformed to this winding drawn out to the load .this
winding is called secondary winding(S) shown in fig.
7. The primary and secondary coil wound on a ferromagnetic
metal core
The function of the core is to transfer the changing magnetic
flux from the primary coil to the secondary coil
The primary has N1 no of turns and the secondary has N2 no of
turns the of turns plays major important role in the function of
transformer
8. WORKING PRINCIPLE
The transformer works in the principle of mutual induction
“The principle of mutual induction states that when the two coils are
inductively coupled and if the current in coil change uniformly then the
e.m.f. induced in the other coils. This e.m.f can drive a current when a
closed path is provide to it.”
When the alternating current flows in the primary coils, a
changing magnetic flux is generated around the primary coil.
The changing magnetic flux is transferred to the secondary coil
through the iron core
The changing magnetic flux is cut by the secondary coil, hence
induces an e.m.f in the secondary coil
9. Now if load is connected to a secondary winding, this e.m.f
drives a current through it
The magnitude of the output voltage can be controlled by the
ratio of the no. of primary coil and secondary coil
The frequency of mutually induced e.m.f as same
that of the alternating source which supplying to the
primary winding b
10.
11. CONSTRUCTION OF TRANSFORMER
These are two basic of transformer construction
Magnetic core
Windings or coils
Magnetic core
The core of transformer either square or rectangular type in
size
It is further divided into two parts vertical and horizontal
The vertical portion on which coils are wounds called limb
while horizontal portion is called yoke. these parts are
Core is made of laminated core type constructions, eddy
current losses get minimize.
Generally high grade silicon steel laminations (0.3 to 0.5mm)
are used
12. WINDING
Conducting material is used in the winding of the transformer
The coils are used are wound on the limbs and insulated from
each other
The two different windings are wounds on two different limbs
The leakage flux increases which affects the performance and
efficiency of transformer
To reduce the leakage flux it is necessary that the windings
should be very close to each other to have high mutual
induction
13. CORE TYPE CONSTRUCTION
In this one magnetic circuit and cylindrical coils are used
Normally L and T shaped laminations are used
Commonly primary winding would on one limb while
secondary on the other but performance will be reduce
To get high performance it is necessary that other the two
winding should be very close to each other
14.
15. SHELL TYPE CONSTRUCTION
In this type two magnetic circuit are used
The winding is wound on central limbs
For the cell type each high voltage winding lie between two
voltage portion sandwiching the high voltage winding
Sub division of windings reduces the leakage flux
Greater the number of sub division lesser the reactance
This type of construction is used for high voltage
16.
17. LOSSES IN TRANSFORMER
Copper losses :
It is due to power wasted in the form of I2Rdue to
resistance of primary and secondary. The magnitude of
copper losses depend upon the current flowing through
these coils.
The iron losses depend on the supply voltage while the copper depend
on the current .the losses are not dependent on the phase angle between
current and voltage .hence the rating of the transformer is expressed as
a product o f voltage and current called VA rating of transformer. It is
not expressed in watts or kilowatts. Most of the timer, is rating is
expressed in KVA.
18. Hysteresis loss :
During magnetization and demagnetization ,due to hysteresis
effect some energy losses in the core called hysteresis loss
Eddy current loss :
The leakage magnetic flux generates the E.M.F in the core
produces current is called of eddy current loss.
19. IDEAL V/S PRACTICAL TRANSFORMER
A transformer is said to be ideal if it satisfies the
following properties, but no transformer is ideal in
practice.
It has no losses
Windings resistance are zero
There is no flux leakage
Small current is required to produce the magnetic field
While the practical transformer has windings resistance ,
some leakage flux and has lit bit losses
20. APPLICATION AND USES
The transformer used in television and photocopy
machines
The transmission and distribution of alternating power is
possible by transformer
Simple camera flash uses fly back transformer
Signal and audio transformer are used couple in
amplifier
Todays transformer is become an essential part of
electrical engineering
