In a transmission line a Fault, is a situation on which causes disturbance to a balanced or unbalanced healthy phase system, so it results to reliability to the supplier and consumer in order to compensate the fault this technique is implemented. Now a days, by using technology a technique on either digital or analog types of protection that can prevent faults on the system by clearing the fault through relays and circuit breakers, their occurrence in detecting and controlling and balancing such unwanted disturbances by using wavelets and it is controlled by using Static Var Compensator.
