Employee Log System Using Pc And RFID
The main aim of this project is to compare the transformer’s load output value continuously with the referenced value and if it exceeds the predefined value, the system automatically transfers the loads to the other transformer and sends a SMS through GSM to the predefined number.
The substation system contains circuit breakers and switches so that the substation can be disconnected whenever necessary. In this project, we are arranging two transformers for the load sharing purposes. A sensor circuit is designed to read the data from the first transformer and if it is found to be in overload condition, the load will be disconnected from the first transformer and will be connected to the next transformer immediately. And a message is sent through GSM to the predefined number. Operational amplifier is used to compare the load of the transformer with a standard load capacity.
Buzzer indication is given by the system whenever the load changes from one transformer to other.
