Remote condition monitoring of high voltage insulators employing GSM network

Remote condition monitoring of power apparatus is a much sought after research area at present. With the existing power network about to be upgraded to a smart grid system in the near future, remote condition monitoring will soon become a critical aspect of the power network. With this in mind, a technique has been proposed in this paper, whereby it is possible to transmit insulator leakage current signal over the GSM voice channel as a means for low cost, yet state of the art, remote condition monitoring system. The scheme proposed in this paper is developed in such a way that it is flexible enough to be applicable to condition monitoring of various power apparatus which employ power frequency signals as analysis tools.
