A compact wireless remote monitoring and control system using embedded and GSM technology

In many areas remote monitoring has been implemented. The application to a single phase energy efficient switchable distribution transformer is introduces in this paper. For the compact remote condition monitoring of the transformer a designed embedded system and embedded Ethernet have been implemented. The embedded system will do the acquisition of voltages, currents and temperatures, it controls the switching devices that connect the tapings of the transformer, and then process the acquired data. Embedded Ethernet will do the client server applications and the remote monitoring is achieved through GSM. As part of the software development some protocols were developed. Experimentation was done by applying remote monitoring to the system connected to the single phase variable supply voltage and load. A result of this experimentation was sent to the computer through GSM.
