This paper deals with experimental investigation on a novel fault location method using air-gap flux distributions of a synchronous generator connected to a power system. Air-gap fluxes are the sum of field fluxes and armature reaction fluxes. Changes in armature current and field current at fault contribute directly to the armature reaction fluxes and field fluxes, then resultant air-gap fluxes. Therefore, air-gap fluxes can be utilized to locate fault. Wavelet analysis is applied to induced voltages of search coils which are wound around a stator tooth top for measurement of air-gap flux. It is shown that fault type and location are estimated from the change of search coil voltages measured during fault.
