A transformer transfers power from one circuit to another through electromagnetic induction without changing frequency. It works on the principle of mutual induction between two coils - the primary and secondary windings. When an alternating current flows through the primary, it produces an alternating magnetic flux that induces an alternating voltage in the secondary. Transformers come in two main construction types - core type with windings on either side of the core, and shell type with windings sandwiched between core limbs. Efficiency losses include copper losses from winding resistance and iron losses from hysteresis and eddy currents in the core.

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.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. What is Transformer ??
A transformer is a
static device which
able to transfer the
power from one circuit
to another circuit
without altering the
frequency .
3. Principle Of Operation
Transformer works on the
principle of mutual induction
of two coils. When current in
the primary coil is changed
the flux linked to the
secondary coil also changes.
Consequently an EMF is
induced in the secondary coil.
4. Primary and Secondary Windings
A two-winding transformer consists of two windings
interlinked by a mutual magnetic field.
– Primary winding – energized by connecting it to an
input source
– Secondary winding – winding to which an electrical
load is connected and from which output energy is
drawn.
5. Working….
When the primary winding is connected to
an ac supply mains, current flows
through it. winding produces an
alternating flux in the core. Since this
flux is alternating and links with the
secondary winding also, so induces an
emf in the secondary winding. The
frequency of induced emf in secondary
winding is the same as that of the flux or
that of the supply voltage. The induced
emf in the secondary winding enables it
to deliver current to an external load
connected across it. Thus the energy is
transformed from primary winding to the
secondary winding by means of electro-
magnetic induction without any change
in frequency.
8. Core type Transformer
In the Core type the
primary and
secondary windings
are placed on each
side of the core.
The core type has
two limbs
9. Shell type Transformer
In Shell type
transformers the LV
and HV windings
are sandwiched
between each other.
shell type has three
limbs.
10. Ideal Transformers
No iron and copper losses
No leakage fluxes
A core of infinite magnetic
permeability
Flux is confined to the core
The windings have zero resistance
An ideal transformer is a lossless device with an input
winding and an output winding. It has the following
properties:
12. Types of Transformer
Step UP Transformer :
A transformer in which Ns>Np is called a step up
transformer. A step up transformer is a transformer
which converts low alternate voltage to high
alternate voltage.
Step DOWN Transformer :
A transformer in which Np>Ns is called a step
down transformer. A step down transformer is a
transformer which converts high alternate voltage
to low alternate voltage.
13. A wide variety of transformer designs are
used for different applications.
Auto-transformer
Poly-phase transformer
Leakage transformer
Resonant transformer
Instrument transformers
15. POLY-PHASE TRANSFORMER
• Three separate single phase
transformers are suitably
connected for 3 phase
operation.
• A single three phase
transformer in which the
cores and windings for all
the three phases are
combined in a single
structure.
16. Losses In Transformers….
The losses that occur in transformers have to be accounted for in any accurate
model of transformer behavior.
1. Copper (I2R) losses. Copper losses are the resistive heating losses in the
primary and secondary windings of the transformer. They are proportional to
the square of the current in the windings.
2. Eddy current losses. Eddy current losses are resistive heating losses in the core
of the transformer. They are proportional to the square of the voltage applied to
the transformer.
3. Hysteresis losses. Hysteresis losses are associated with the rearrangement of the
magnetic domains in the core during each half-cycle. They are a complex,
nonlinear function of the voltage applied to the transformer.
4. Leakage flux. The fluxes which escape the core and pass through only one of
the transformer windings are leakage fluxes. These escaped fluxes produce a
self-inductance in the primary and secondary coils, and the effects of this
inductance must be accounted for.
17. Efficiency of a Transformer
Transformer efficiency may be defined as the ratio
between Output and Input. Efficiency = Output/Input
• Efficiency = η= Output / Input
• Efficiency = η= Output / (Output + Losses) …….… (As
Input = Output +Losses)
• Efficiency = η= Output / (Output +Cupper Losses +
Iron Losses)
You may also find the Efficiency by the following formula
• Efficiency = η = (Input – Losses) / Input …….… (As
Output = Input – Losses)
Taking LCM
• Efficiency = η = 1 – (Losses /Input)
18. What is Voltage Regulation ?
The voltage regulation is the change in terminal voltage of the secondary from
no load to full load voltage.
