Abstract
According to an embodiment, a field winding interlayer short-circuit monitoring device comprises: an input unit configured to obtain field winding current values and field winding voltage values at a predetermined sampling cycle; a memory configured to store field winding resistance versus current characteristic curves at an abnormal state and a normal state; and a field winding resistance calculator configured to calculate a field winding resistance value by dividing the field winding voltage value by the field winding current; an average value calculator configured to calculate an average resistance value and an average current value by averaging those obtained during a predetermined time interval; and an image data generator configured to generate image data to display a predetermined number of average value data along with the field winding resistance versus current characteristic curves at the normal state and the abnormal state.
