Abstract:

The electricity demand is increasing day by day as a result, there is a need to transmit more power from one place to another. This paper presents detection, classification and location of the fault in the power system. The measurement of bus voltage and RMS current values are used in this scheme. Detection of fault is done by continuous measurement of voltage and currents before and after the occurrence of the fault. Fault classification is done by using the Wavelet transform technique using the MathLab and the Magnetoresistance sensor based method is used for the location of the fault. When there is a fault detected, the information about the fault is sent to the service provider as well as to the consumers. This process has to be more accurate so that system reliability can be improved, the maintenance and the restoration of the fault condition can be accelerated.
