AIM:
The main aim of this project is to monitor and record key operation indictors of a
distribution transformer like load currents, voltages and ambient temperatures.
PURPOSE:
The purpose of this project is to send the information to the mobile by using GSM
technology about the distribution transformer operations like load currents, voltages and
ambient temperature. If there is any abnormality or an emergency situation the system
sends SMS (Short Message Service messages to designated mobile telephones.

DESCRIPTION:
This project presents design and implementation of a mobile embedded system to
monitor and record key operation indictors of a distribution transformer like load
currents, voltages and ambient temperatures. The proposed on%line monitoring system
integrates a Global Service Mobile (GSM Modem, &ith stand alone single chip
microcontroller and sensor packages. It is installed at the distribution transformer site and
the above mentioned parameters are recorded using the built%in '%channel analog to
digital converter (#$ of the embedded system.
The ac)uired parameters are processed and recorded in the system memory. If there
is any abnormality or an emergency situation the system sends SMS (Short Message
Service messages to designated mobile telephones containing information about the
abnormality according to some predefined instructions and policies that are stored on the
Micro ontroller. #lso, it sends SMS to a central database via the GSM modem for
further processing. This mobile system &ill help the utilities to optimally utili*e
transformers and identify problems before any catastrophic failure.
TECHNOLOGY: +very system is automated in order to face ne& challenges in the present day
situation. #utomated systems have less manual operations, so that the fleibility,
reliabilities are high and accurate. -ence every field prefers automated control systems.
+specially in the field of electronics automated systems are doing better performance.

robably the most useful thing to kno& about the global system for mobile
communication is that it is an international standard. If you travel in parts of &orld,
GSM is only type of cellular service available. Instead of analog services, GSM &as
developed as a digital system using T$M# technology.
