Monitoring and Protection of Distribution Transformer Using GSM Module
Abstract:
The aim of the project is to design a monitoring and protection system for distribution transformer with the
help of GSM and GPS technology. The present monitoring system requires manpower which is time-consuming and
it is difficult to predict the occurrence of faults. In this project, we designed a system which continuously monitors
the transformer parameters such as load current, voltage, oil level and ambient temperature with the help of sensors.
These values are displayed continuously on the LCD display and it is recorded in the system memory. If any
abnormalities occur in the transformer then an alert message with the parameter values are sent to the monitoring
centre along with the location by means of GSM and GPS which are integrated with the Arduino board. This system
will help the transformer to operate smoothly and identify problems before any catastrophic failure.

the condition and it places the high signal on A0 pin and then
the Arduino transmits the signal to GSM and GPS which in
turn sends the message to the programmed number.
By the same way, oil level was lowered manually and the
message was received and the fault was displayed on the
LCD display.
A server module can be included in this system for receiving
and storing transformerparameters information periodically
about all the distribution transformers of a particularutility in
a database application. This database will be a useful source
of information on the utility transformers. Analysis of these
stored data helps the utility in monitoring the operational
behaviours of their distribution transformers and identify
faults before any catastrophic failures thus resulting in
significant cost saving as well as improving system
reliability.
VI. CONCLUSION:
The complete design of the model is given and the circuit of
monitoring and protection of distribution transformer is
successfully implemented and the desired result is obtained.
Manually the oil level was made low below the limit
instantly our monitoring system detects the fault and trips the
circuit along with sending a message to the specified
number.
