INTRODUCTION
• Rise in operating temperature of the transformer due to overloading has an influence on
ageing of transformers.
• The accelerated aging is one of the main consequences of overloading power
transformers. Thus load limitations must be implemented to operate the transformers
within safe limits.
• Moreover on overloading the transformers voltage regulation may increase and power
factor drops. The project is all about protecting the transformer under overload
condition.
• This can be done by connecting another transformer in parallel through a
microcontroller and a relay which shares the excess load of the first transformer. The
transformers are switched alternatively to avoid thermal overloading.
• Also smart monitoring system using LCD display, to see the information all parameters.

COMPONENT SPECIFICATION
TRANSFORMER :
• Transformer is a static device which consist of two or more stationary
electric circuit interlinked by a common magnetic circuit for the purpose of
transferring electrical energy between them.
• The transfer of energy from one circuit to another takes place without
change in frequency.
• In this project we are using 2 transformer- main.
• Rating of both the transformers- 230/12v & 1A.
CURRENT SENSOR :
• ACS712 Current Sensor Module 20A is based on ACS712
sensor, which can accurately detect AC or DC current.
ARDUINO
•UNO
Arduino
: is an open-source electronics platform based on easy-to-use
hardware and software. ATmega328P is a high performance yet low power
consumption 8-bit AVR microcontroller that's able to achieve the most
single clock cycle execution of 131 powerful instructions thanks to its
advanced RISC architecture.
• The board is equipped with sets of digital and analog input/output (I/O)
pins that may be interfaced to various expansion boards (shields) and
other circuits.
DEVELOPMENT BOARD :
• The board is equipped with sets of digital and analog input/output (I/O)
pins that may be interfaced to various expansion boards (shields) and other
circuits.
• Input Voltage 9v -12v DC.
• IC 7805 Power module is place over development Board for conversion
of
RELAY BOARD
•: A relay is usually an electromechanical device that is actuated
by an electrical current. The current flowing in one circuit
causes the opening or closing of another circuit. Relays are like
remote control switches and are used in many applications
because of their relative simplicity, long life, and proven high
reliability.
LIQUID CRYSTAL DISPLAY :
• A liquid crystal display is a mode of display used in digital equipment
replacing many other modes of displays such as cathode ray tube, LED
displays and plasma displays. Often abbreviated as LCD, liquid crystal
displays are a thin flat panel which is made up of several blocks filled
with liquid crystals.

ADVANTAGES
• Increase Reliability of power System.
• Parallel Operation of transformer minimize the transformer losses.
• Automation of Load sharing reduce human interference
APPLICATION
• Power Generation and distribution system.
• Process Industry
• Protection from overloading of transformer
• Uninterrupted power supply
CONCLUSION
In this project of Automatic Load Sharing of Transformers Using
Microcontroller, a technology is implemented to share the load on the
transformers. This provides un-interrupted power supply and avoids
blackout in particular areas where there is varying loads. With the
advancement of communication technology, now it is possible to receive
overload condition of transformer through LCD display to the control room.
During overload condition exceeding specified limits information is
immediately communicated through display technology to the concerned
authority for possible remedial actions. Hence the transformer is protected
from the overload condition and uninterrupted power supply is available to
the consumers.
