Objective
  • In this project, the idea to protect the
    transformer from unauthorized person is mainly
    come from the national problem of the rural area
    of Bangladesh. Day by day Transformer stolen by
    the unauthorized person became a verse problem.
    Because of this problem every year huge amount of
    money go in vain. Especially for the people of
    rural areas, it is very difficult to bear this
    amount. So the project is established by
    considering this great problem.
  • It is noted that 31st March 2010 The national
    daily newspaper Prothom-alo also published a
    article on it.

Transformer
  • A transformer is a device that transfers
    electrical energy from
  • one circuit to another. Transformers are
    essential for high voltage to low voltage or vise
    verse. So to give the protection of this
    important device this circuit has been
    implemented.

5
Overview of the product
  • In this project a non-inverting Op-Amp is
    used to compare the on/off conditions which will
    be provided by the two neutrals (one is connected
    to the Transformer side another is connected to
    the customers side). With the disconnection of
    the line the amplifier will send off condition
    (zero). Then it will be inverted to on condition
    (one) and send it to the relay. After the
    activation of that relay it will contact the
    switch to the device, and then a signal will send
    the central control room. Until the authority
    takes any action, it will ring. Under load
    shedding also it can be operate, because a charge
    controller device is connected to the circuit
    which will give backup to the device. The whole
    device should be packed in an isolated box and it
    will be attached to the Transformer.

6
Reason for selecting Mobile Network
  • Grameenphone was able to keep 98 of its entire
    network operational throughout the critical first
    36-hour period after the cyclone, which battered
    the Khulna-Barisal coastal belt and passed
    through the country.
  • Grameenphone has over 15000 base stations sites
    located around the country.

7
Background of the Product
  • A transformer is a device that transfers
    electrical energy from one circuit to another
    through inductively coupled conductors the
    transformer's coils.
  • Transformers are essential for high voltage
    power, which makes long distance transmission
    economically practical.
  • It is major part of Electricity transmission. So
    that it is important for us that it should be
    kept safe from being wasted. That is how the idea
    of the transformer protection got introduced.

Implementation
This circuit has been implemented for the
protection of the transformer in the rural areas
of Bangladesh. There are two switches which has
been connected to the neutral. One from
transformer neutral side and another from
customers. Depending on the ON/OFF situation the
circuit has been implemented. Then the output
will send to the communication device ,then it
will passed the information to the control room
and it will identify the location of the problem.

Operation of the circuit
Case
  1. When T and C both are close then output show on
    1.1V approximately, after inverted (using NOT
    gate) the output show zero volt and relay does
    not operated. Figure is shown below

12
II. When T is close and C is open then
output show on 1.1V approximately, after inverted
the output show zero volt and relay does not
still operated. T is represented by Transformer
side neutral and C is represented by customers
side neutral. Figure is shown below
13
III. When T is open and C is close then
output near to zero after Inverted
(using NOT gate) the output show 1V and
relay is close and conduct to mobile device for
transmitted the signal to control room. Figure is
shown below
14
IV. When T and C both are open then output
near to zero after Inverted (using NOT gate) the
output show 1V and relay is close and conduct to
mobile device for transmitted the signal to
control room. Figure is shown below

PCB Layout
  • A printed circuit board or PCB, is used to
    mechanically support and electrically connect
    electronic components using conductive pathways,
    tracks or signal traces etched from copper sheets
    laminated onto a non-conductive substrate.
  • Need for PCB
  • No wires
  • Makes a design permanent
  • In industrial scale production of circuits
  • So the circuit has been implemented also in the
    PCB board.

Cost of the Product
  • The cost of my invented Product or Device is only
    BDT 5000.That way every rural area poor people
    easy to buy for protect his / her area's
    Transformer from Thief. And Also Our Bangladesh
    Govt. can also buy our device at lowest cost. If
    the 1st time any problem occur in the transformer
    then govt. will give the support but if it is
    happened again then consumer itself have to take
    the responsibility. In  case they will might have
    to bought the transformer which prize is
    60000-80000.So that amount of prize is not
    possible to afford our rural areas people.
    Thats  why our invented device is only BDT 5000
    , that help to protect Transformer from
    Unauthorized person (Thief).

23
Future Work
  • The circuit which has been designed in this
    project is capable to meet the demand of the age.
    It provides a lot of facilities. It is cheaper
    and lighter. And the requirement that has been
    used is also available. It provides the consumer
    with the opportunity to have the record the
    information. Though this project is successful to
    detect the problems but it wont be fruitful
    without any physical development. By doing some
    additional work it can be developed. suppose by
    using a sensor (to sense the problem),alarm(to
    give alarm to the control room) and a display
    board (To identify the problems location) it can
    be developed.

Paper Published
  • In my B.Sc in Electrical Electronic Engineering
    (EEE) course in the part of Project Thesis in a
    group work me and my others members we invented a
    device which could protect Transformer from
    stolen at the rural area those are control by
    Rural Electrification Board (REB). This is
    renowned by REB members engineers. Also
