Field winding interlayer short-circuit detection apparatus and field winding interlayer short-circuit detection method
According to the embodiment, a field winding interlayer short-circuit detection apparatus comprises: a field winding resistance calculator to calculate, for a field winding of a rotating electrical machine, a field winding resistance calculated value from a detected value of a field winding current and a detected value of a field winding voltage; a determiner to determine presence or absence of an interlayer short-circuit in the field winding by using a comparison result between the field winding resistance calculated value and the reference resistance value.
