Abstract: Power is essential need for the economic development of any country. Power stations, transmission lines and distribution systems are the main components of an electrical power system. Analysis of different types of fault is an important and complex task in a power system. Accurate determination of fault location distance to fault in transmission lines. The mathematical models accurately calculate the impedance and actuate the corresponding circuit breaker depending on the value of impedance. Aim of this study is to design a distributed parameter line model and devise a system to distinguish between faults in a nearby zone and a remote zone. The method used in this study is to detect the fault as a ratio of volt/ampere method. To analyze this method an algorithm based on mathematical model short line which utilizes unsynchronized data from sending end of the transmission line. The samples of recorded voltage and currents are used for the calculation of distance. These current and voltage samples are used to develop algorithm in LabVIEW to obtain faulted impedance of a line. LabVIEW Software is a graphical programming language that is program with function blocks replacing text based programming can bring our vision to life with LabVIEW.
