1. AUTOMATIC POWER FAILURE INDICATOR TO EB
SUB STATION
ABSTRACT
This
project is developed for the users to identify the power failure in houses and
industries and to inform the EB in wireless manner. It consists of power sensor,
microcontroller unit, multi channel RF transmitter and receiver, LCD display etc.
In the house/industries, the microcontroller unit is connected with the power line
through power sensor. The status of electricity is sensed by the microcontroller. In
the time of power failure, the sensor sends signal to the microcontroller.
The
microcontroller analyses the signal and accordingly it sends signal to the multichannel RF transmitter.
In the EB Office, a multi channel RF receiver is connected. The receiver receives the
signal from the house/industries and sends corresponding signal to the microcontroller
unit. The microcontroller sends corresponding signal to the LCD display and thus the
display displays the status of power in the house/industries.
