Fault Analysis and Electrical Protection of Distribution Transformers
The demand on the electric power for the household, commercial and industrial loads is on the increase. Also, the management of electric distribution system is becoming more complex. Lack of information at the base station regarding status of the distribution network has been identified as the major bottleneck to its effective monitoring and control. The work described is a development of Microcontroller-based Protection of Electric Distribution system for the purpose of effective monitoring and control of distribution system. A powerful GSM networking is designed to send data from Distribution side to the Sub-station and a Matlab GUI system has been develop to show the data. In general, the proposed design is developed for the user to easily recognize the distribution transformer is safe or unsafe and the distribution line that is suffered by fault. The ultimate objective is to monitor the distribution line status continuously and hence to guard the fault of distribution line due to the constraints such as overvoltage, under voltage, SLG, DLG faults. If any of these does occurs then a message will be sent to the designed controlling unit or substation.
