| dc.description.abstract | Power has been and is the integral part of every walk of life in the modern human history. In the event of power transmission to appliances, transformer plays key role. As with all, if not most, electrical devices, a transformer requires real-time monitoring and proactive protection mechanisms to properly function and remain safe. On top of that, thievery of the equipment phenomenon of reality befalling more often. This study, therefore, simulated a SCADA based distribution transformer monitoring and protection system for Ethiopian Power Utility to alleviate the aforementioned concern. The simulation demonstrates protection and monitoring of transformer parameters namely oil temperature, winding temperature, oil level, load, voltage, and theft protector with the help of codes, sensors and pertinent software. The codes were written using Arduino MEGA 2560 (microcontroller) and it basically receives current values of each parameter via the sensors, evaluated to standards, takes corrective action and displays the figures. The code compiled in to (.hex) files and loaded to the Arduino for executions. The monitoring and protection system consists of block diagram and circuits of all the parameters, cooling fans, different sensors for oil level, oil temperature, winding temperature and theft detector made using proteus (ISIS professional). The SCADA system is displayed using LABVIEW where data reading and writing are enabled. The proteus and LABVIEW software were connected by VSPE (virtual serial ports emulator). The overall simulation system was found to operate pretty well with all the settings of the parameters satisfied. The system responds to normal operations and abnormal conditions of distributed transformer under functioning. The state of each parameter was able to monitor and protection of the distributed transformer guaranteed when conditions went wrong.
