Abstract	Electrical machines, installed in different locations in a plant for a typical application, are needed to be monitored and controlled for their healthy operation and smooth running of the plant. This is mainly done by manual observations at the machine sites. It is not alaways possible, rather difficult, to keep track all the machines at a time. On the otherside, modern civilization is advancing at very faster pace with the adoption of wireless technology. The convergence of wireless technology and the embedded technology makes the wireless systems more reliable, much efficient as well as cost effective one. Keeping this in mind, the present approach has been made to apply the advantages of wireless communication and embedded technology towards electrical machines automation. This paper describes the development of a centralized automated system for remote monitoring, analyzing and control of electrical parameters of different machines of a power station, sub-station or any plant so as to enhance the overall system performance using GSM communication. In this scheme, a state-of-the-art stand alone control card is developed for monitoring the power system parameters like instantaneous voltage, current and instantaneous Power and power factor, frequency, speed, torque and temperature of a machine in a typical plant. The card is response for measuring and control of the machine parameters and hence located at the machine site with one card per machine basis. The card is also interfaced with GSM modem for remote wireless accessing. There will be multiple card for multiple machines control. On the remote end, a centralised PC is used for central access of the individual machine. Hence, this PC is interfaced with another GSM based state-of-the-art control card. PC software is designed in such a way that, it can access any machine with all its parameters appearing on to the screen at any instant of time and the data is stored for future analysis. With this analysis, a diagnostic tool for any incipient fault of a machine can be developed.
