Abstract
This
project aims at continuously monitor the load conditions of the
substation. It also monitors the temperature of the devices present in
the substation. If the load increases beyond the substation’s rated
capacity, the microcontroller will automatically shut down the
substation.
If
the temperature of the substation increases, then the microcontroller
will automatically starts the cooling system for the substation. If the
voltage ratings of the loads increase beyond the rated values, the
system immediately shuts down the substation i.e., the power will be
disconnected to the substation from the mains supply.
The
controlling continuously monitors the temperature through temperature
sensor LM35 and the voltage of the loads through voltage measuring
circuit. ADC is used to convert the read analog values into their
corresponding digital data. If any of the values exceed its rated
values, the controlling unit immediately performs the specified action.
