This paper describes a condition reporting system of Power plant components using GSM technology. Most of the reporting systems commonly used in Myanmar are manual. The objective of this paper is to transform manual system to automated reporting system with the help of GSM technology. There are three portions in automated reporting system. They are GSM modem system, microcontroller system and sensing system. A dedicated microcontroller based hardware unit (DHU) has been developed to continuously measure the parameters of the viz. voltage, current and temperature of generation of the alternator to monitor the running condition of it also. Other than the generator there are subsystems which also need continuous monitoring. In this monitoring system equipment is connected with one such DHU which is also connected to a Global System for Mobile Communication (GSM) modem. The preliminary level of fault or abnormality in operation of component is diagnosed by the DHU and the fault or abnormalities details are reported to the pre-assigned operator through an SMS service. In extreme case, the provision of equipment shut down by a return SMS is also provided. The circuit model has been set up and is working satisfactorily.
