This is a modern technique of Monitoring of switchyard which is used in many other countries.
It will be useful for reducing requirement of manpower.
When a fault occurred a SMS will be sent to the registered mobile number detailing about type of fault and location of fault.
GSM Based Fault Monitoring System

The goal of this presentation is to explain
working of our project GSM Based Fault Monitoring
It helps to monitor the Power Grid, Industry.
We have no need to put a person on relay room to monitor
the Fault/ Relay .
This project designs an indication system with overvoltage and

Each type employs internal current limiting, thermal shut
down and safe operating area protection, making it
Although designed primarily as fixed voltage regulators,
these devices can be used with external components to
obtain adjustable voltages and currents.
The LM78XX series of three terminal positive regulators.
consist of two independent,
high gain, internally
which were designed
specifically to operate from
a single power supply over a
wide range of voltage.
The following are some of the
capabilities of 8051
1. Internal ROM and RAM
2. I/O ports with programmable
3. Timers and counters
4. Serial data communication
Relay unit has been designed to
operate in accordance with the
switching signal and controlled
Following are the points upon
which relay has been selected:
Operating voltage- Should lie
between 5V – 12V
Equipped with NO an NC
In this Project GSM
Modem is used to develop a
Interface between Mobile &
Microcontroller by using
It connects Microcontroller
to network provider to send
We are giving power supply through adapter.
Bridge rectifier is used to convert AC into DC.
Filter circuit is used to removes the unwanted
repulses and its output is fed at the input terminal
of LM78XX series regulator.
The 12V constant Voltage is fed to Relay & 5V
is fed to the Modem & Microcontroller.
sends sms “ Industrial
fault Monitoring device” when we on
When fault occur relay trips & after
some time a SMS will be send to the
predefined number about type of fault.
SCOPE FOR FUTURE ENHANCEMENT
The scope for the future enhancement of the
circuit is also shown in the block diagram. If an
amplifier connected to the motor or various other
equipment at the power grid is connected to the
microcontroller circuit and suitable programming
is done then along with the fault detection
controlling of power grid can also be done by the
use of GSM technology.
A message will be sent on the number of Supervisor
when the fault occur in the transmission system.
No need to monitor from the Relay room.
Negligible electricity consumption
Easy to Install
No Maintenance Required
Very affordable price
need to monitor from relay room.
System can be monitored and controlled from
Save men work.
Mobile number can be changed at any time.
Area of Application
The major areas captured by it are :
And many more…………..
All the components must be as per the circuit
Microcontroller & LM78XX should be mounted on the
Modem tower must be in vertical position for good
I. C. should not be heated much while soldering; too
much heat can destroy the I.C.
Opposite polarity of Supply can destroy I.C so please
check the polarity before switching ON the circuit.
Conclusion & Results
Hence by this project we can Monitor the
fault at power grids using GSM Based Mobile
by means of SMS.
Grid status will not be lost in power failure
