OVER LOAD CUTOUTS FOR SUBSTATION
Aim: The aim of the project is to protect the
substation from over loads.
The Project “Overload cutouts
for substation” using Microcontroller is a reliable circuit that takes over the
task of protecting the substation from over loads very accurately. Now a days, usage
of power increased enormously for households. The over usage of power leads to
over load on substations and the potientiometer always monitor the variation of
voltage in substation and it sends to controller continuously.So, protecting the substation from overloads a
microcontroller based cutout circuit is takes the task for protecting the substation.
The microcontroller does the
above job. When ever the load exceeds beyond the capacityof substation.the
controller switch off the complete
substation.micro-controller 89S51 continuously monitor the load,load exceeds
and it will switch off the substation.
The implementation is made
simpler by potientiometer. The system
includes potientiometer , microcontroller, LCD display and a 5v power is
supplied to run the system.
The system uses a compact
circuitry built around 8051 microcontroller Programs are developed in Embedded
C. Flash magic is used for loading programs into Microcontroller.
