Multiple Transformers Oil Temperature Monitoring With Automatic Circuit Breaker

Multiple Transformers Oil Temperature Monitoring With Automatic Circuit Breaker Operation With SMS Based Alerts


[attachment=50819]

Introduction

Transformer is a very vital device in all the industries and it is one of the most important and expensive device in the power industries.
Any failure in this component may lead to serve consequence as to economic and safety aspect.
But now a day when the industries are running 24×7,there is a chance of heating down the transformer, due to increase in oil temperature used in the transformer .
We cannot afford this development, because this leads to loss of money and time.  

REQUIREMENT OF OIL TEMPERATURE MONITORING

PROTECTS THE TRANSFORMER FROM DAMAGE.
LIFETIME OF TRANSFORMER CAN BE INCREASED.
SINCE OIL IS PRESENT IN THE TRANSFORMER THERE IS A NECESSITY TO DEVELOP A SYSTEM WHICH CAN
SENSE THE TEMPERATURE OF OIL INSIDE THE TRANSFORMER.
AUTOMATICALLY SWITCH ON THE CIRCUIT BREAKER IF TEMP EXCEEDS LIMIT.
ALERT THE ELECTRICITY DEPTT THROUGH SMS.

HARDWARE REQUIREMENTS

MICROCONTROLLER AT89C51 IC
LCD
TEMPERATUR SENSOR 
LED
TRANSFORMER 
REGULATOR 
ELECTRICAL COMPONENTS

MICROCONTROLLER AT89C51 IC

AT89C51 MICROCONTROLLER 


Compatible with MCS-51™ Products
4K Bytes of In-System Reprogrammable Flash Memory 
–Endurance: 1,000 Write/Erase Cycles
Fully Static Operation: 0 Hz to 24 MHz
128 x 8-bit Internal RAM
32 Programmable I/O Lines

Temperature Sensor(LM35)

These sensors use a solid-state technique to determine the temperature.
The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (centigrade) temperature.
LM35 does not require any external calibration.
The LM35’s low output impedance, linear output, and precise inherent calibration make interfacing to readout.
It can be used with single power supplies.

Importance of LM35 sensor

The sensor circuitry is sealed and not subjected to oxidation, etc.
 You can measure temperature more accurately than using a thermostat.
The LM35 generate a higher output voltage than thermocouple and may not require the output voltage be amplified.
Rated for full -55˚ to +150˚C range.
Operates from 4 to 30 volts.
Low cost due to wafer-level trimming.

CONCLUSION

This project has presented a design of a system based on microcontroller that is used to monitor and control the temperature of a distribution transformer.
The proposed system which has been designed to monitor the transformer’s essential parameters continuously monitors the parameters throughout its operation.
If the microcontroller recognizes any increase in the level of temperature values the control relay will break the circuit in order to prevent it from further damages.
