Resumen
System and process for locating ground faults in armature windings of synchronous machines. It treats of a system that allows to locate the faults to earth in estatores of synchronous machines without realizing the extraction of the rotor of the machine and without damaging the magnetic packet of the same. It includes: - an alternating voltage source (3) with which the field winding or inductor (rotor) of the machine (1) is fed; - a set of equipment for measuring the voltage induced in the phase or branch of the winding with the earth fault and in any of the phases or branches without defect. - a system for calculating the percentage of winding short-circuited, which will operate by: - measurement of the voltage induced in the phase or branch of the winding with the earth fault. - measurement of the voltage induced in any of the phases or branches without defect. - calculation of the percentage of the winding with defect from the two previous measurements.
