10. Function of Transformer Oil
To provide dielectric strength of
the transformer insulation system
To provide efficient cooling
To protect the transformer core
and coil assembly from chemical
attack
To prevent the build up of sludge
in the transformer

12. Importance of Sensor
Measure temperature more
accurately than using a
thermostat
Generate a higher output
voltage than thermocouple
Rated for full -55˚ to +150˚C
range
Operates from 4 to 30 volts
Low cost

15. Importance of Regulator
Provided with maximum
threshold temperature after
which X-former need to turn
off
Controller also displays the oil
temperature over an LCD
display
Gives Permission to circuit
breaker to disconnect the Xformer from power line

18. Getting Information
GSM modem is used for
sending the information of
critical situation of Xformer
Alerts the electricity
department through SMS

19. Monitoring
 Monitored as soon as
SMS reached through
GPS
