Electrical power transmission systems suffer from unexpected failures due to various random causes. Un-predicted faults that occur in power systems are required to prevent from propagation to other area in the protective system. The functions of the protective systems are to detect, then classify and finally determine the location of the faulty. This paper presents some techniques that helps to find, determine and diagnosing faults in transmission line. Artificial neural networks, impedance measurement based methods, fuzzy expert method, wavelet transform and so on have been used to achieve fault identification and classification.This paper will review the type of fault that possibly occurs in an electric power system, the type of fault detection and location technique that are available together with the protection device that can be utilized in the power system to protect the equipment from electric fault.

Excerpt from the Book
IV. OVERVIEW OF TRANSMISSION LINE FAULTS
Transmission line fault could not be avoided in an electrical power system, some protection devices are needed to protect the expensive equipment in electric power systems before the fault occurrence. But after the fault occurs once on the system we must determine fault locations and types for maintaining the system. Because of those reason, we will design smart devices and techniques in our system [28].
A. Causes transmission line faults
The most common causes of faults in overhead lines are [78]:
Aircraft and cars hitting lines and structures
Birds and animals
Contaminated insulators
Ice and snow loading
Lighting
Partial discharges (corona) not controlled
Punctured or broken insulators
Trees
Wind and so on.
