Abstract

The Electrical power transmission and distribution power lines plays vital roles in Power System techniques it has to achieve the essential continuity of service of power source to the end users. The power transmission lines connect the generating stations and load centers. The probability of fault occurrences in transmission lines is very high. Since a faults can destabilize the power system it must be isolated immediately for restoration of power source. It is fault analysis is very important issue in power technique engineering in order that to clear faults quickly and restore power supply as soon as possible with minimum interruption. In this paper presents a literature review of power transmission line faults detection.

Introduction

The electric transmission system faults are the greatest threat to the continuity of electricity transmission. The faults on electric power are an unavoidable problem. A well-coordinated protection scheme must be provided to detect and isolate faults rapidly so that the damage and disruption caused to the power system is minimized. It is therefore an everyday fact of life that various types of faults on electrical power systems, though infrequently, and at random locations. The power system is faults can be broadly classified into two main areas which have been designated as active and passive. The electrical power systems control centers contain a large number of alarms received as a result of various types of faults. To protect these systems, the faults must be detected and isolated accurately. Majority of shortcircuit faults tend to occur on overhead lines. The operators in the control centers have to deal with a large amount of data to get the required information about the faults. The faults occur when various conductors contacted with ground or each other condition. In fault detection and isolating the faulted line quickly is important since faulted lines may cause accidents which may harm human, and damage the equipment’s or decrease the economical life of devices because of short circuit current. The faults may lead to new faults in other power transmission lines or substations. Furthermore, the interrupts will decrease the quality electricity supplied. Therefore, many approaches were introduced to solve this issue.

Conclusion

The various papers and literature has been studied for fault detection. Most of the prose worked on detection of fault related to the power system.For the improvement of power quality meaning that to make power purer, the compensated circuit is considered to be attached. While to enhance the power system with reliability respected time. Thus more important is to detect of fault as well as locating them as soon as possible.
