The fault location detection has been a goal of power system engineers, since the creation of distribution and transmission systems. Quick fault detection can help protect the equipment by allowing the disconnection of faulted lines before any significant damage of the equipment. The accurate fault location can help utility personnel remove persistent of the faults and locate the areas where the faults regularly occur, thus reducing the occurrence of fault and minimize the time of power outages. As a result, while the fault location detection schemes have been developed in the past, a variety of algorithms continue to be developed to perform this task more accurately and more effectively. The detection and location of faults on power transmission lines is essential to the protection and maintenance of a power system. Most methods of fault detection and location relate to the measurements of electrical quantities provided by current and voltage transformers. These transformers can be expensive and require physical contact with the monitored high voltage equipment.
The main objective of this project is to monitor the transmisison line with the real time monitering using software.
The project helps us to monitor the theft condition of the transmisison line.
The project helps us to monitor the fault presence in the transmission lines.
The software system helps us to monitor the sending and the recieving power.
incase of theft the purposed system helps us to disconnect the trasmisison line in which power theft occours.
The implementation of this hardware is diveded into two main catagories.
1) Software Designing
2) Hardware Designing
The software is designed using the visual studio for the controlling of the hardware.
The hardware is designed with the help of arduino uno r3 which will works as a brain of this hardware.The arduino and the software detects the any faults and the theft in the transmisison line and with the helps of relay the arduino will disconnect the supply of transmission line.

CURRENTLY, the electric power infrastructure is highly vulnerable against many forms of natural and malicious physical events [1], which can adversely affect the overall performance and stability of the grid. Additionally, there is an impending need to equip the age old transmission line infrastructure with a high performance data communication network, that supports future operational requirements like real time monitoring and control necessary for smart grid integration. Many electric power transmission companies have primarily relied on circuit indicators to detect faulty sections of their transmission lines. However there are still challenges in detecting the exact location of these faults. Although fault indicator technology has provided a reliable means to locate permanent faults, the technical crew and patrol teams still has to physically patrol and inspect the devices for longer hours to detect faulty sections of their transmission lines. Wireless sensor based monitoring of transmission lines provides a solution for several of these concerns like real time structural awareness, faster fault localization, accurate fault diagnosis by identification and differentiation of electrical faults from the mechanical faults, cost reduction due to condition based maintenance rather than periodic maintenance, etc.. These applications specify stringent requirements such as fast delivery of enormous amount of highly reliable data. The success of these applications depends on the design of cost effective and reliable network architecture with a fast response time. The network must be able to transport sensitive data such as current state of the transmission line and control information to and from the transmission grid. This research provides a cost optimized framework to design a real time data transmission network. To monitor the status of the power system in real time, sensors are put in various components in the power network. These sensors are capable of taking fine grained measurements of a variety of physical or electrical parameters and generate a lot of information. Delivering this information to the control centre in a cost efficient and timely manner is a critical challenge to be addressed in order to build an intelligent smart grid. Network design is a critical aspect of sensor based transmission line monitoring due to the large scale, vast terrain, uncommon topology, and critical timing requirements. Mechanical faults, cost reduction due to condition based maintenance rather than periodic maintenance, etc. The use of sensor networks has been proposed for several applications like mechanical state processing and dynamic transmission line rating applications .To monitor the status of the power system in real time, sensors are put in various components in the power network.
