In Electrical system there is an interrupted system called Fault, a connection or a situation that causes an unbalance among the three phases. That can be broken down into three groups of balanced vectors. When all the factors have been tentatively selected and balanced, they should be checked by calculations for the limiting the fault condition.
Such calculations can be made by hand but are very laborious if more than two generating stations are involved, and in such cases the use of the a-c calculating board is the only satisfactory means of solution. Foregoing discussion has treated transient stability when faults occur.
However, a first consideration in system design is the prevention of faults. This includes such factors as clearances, ruggedness of structures, lightning-diverting cables and towers, and guards against birds and animals.
The researcher chooses the topic “Faults on Electrical System” to discuss the types fault systems on how to be cleared out into the system, another form that will satisfy on the electrical system.
Statement of the Problem
In general, transient instability results when the flow of synchronizing power between generating stations during and following a fault is insufficient to overcome the speed changes acquired by the generators during and following the disturbances quickly enough to prevent faults, system design are usually requires that transient stability shall be maintained if the most important interconnecting line of a network shall be tripped out due to one or more of the faults which may be experienced.
Transient stability for three phase faults on the main lines of a transmission system is to be cleared.
The Researcher picks the topic “Faults on Electrical System” to determine the importance of the faults and to eliminate them to the system.
