7. THREE PHASE TRANSMISSION LINE AUTOMATIC FAULT DETECTION

“Power System” is the most important in the world. Power system is consist and divided in many sections as like generation, transmission and distribution. Transmission lines are assumes significant part in power framework. In this framework power is sent from creating station to the dispersion framework and afterward towards buyer end with the assistance of Transmission Line just as circulation framework. While sending the force causes different kinds of failing and undesirable and unfortunate episodes is generally called as "Flaws." Faults make aggravation in power framework and harm transformer. In typical stable condition issues happens when the protection comes up short at the any area of the framework. A three stage transmission line programmed shortcomings recognition framework is utilized to precisely and enough show what is the issue had accurse. It saves the time and endeavors of experts to redress these flaws. It save transformer just as force framework from mechanical harm and fiasco. In this system by using Arduino Nano, microcontroller 238p. The system automatically detects the faults. System will analyses and classifies those faults and calculate the faults nature, locations and distance from the control room. Using algorithm methods the accurate information of faults is transmit to control room and indicate the fault nature and location. Finally we conclude using this system we save the time and reduce the extra efforts of line patrolling wok.
