Effect of Electrical Power line length on Faults occurrences in Electrical Distribution SystemA case study of Ayede 132/33kV substation

The paper examined the state of distribution network and analyzed the main causes of faults using Ayede 132/33kV as a case study. At the time of the study, the state of the major electrical facilities for 33kV distribution system was assessed to exploit information available related with the causes of faults. In addition, frequencies of faults occurrences on the feeders emanated from the substation as well as their lengths were obtained and were compared to know the effect of length of feeder on number of fault occurrence. In view of the findings during the cause of investigation, it is evident that the physical equipment needs urgent rehabilitation. Likewise, lengths of some feeders are too long compared to the magnitude of power they are transporting and required higher voltages for transmission.
