摘要：
The invention provides an insulation fault to an electrical machine (24) having a rotor (26) and a stator (28),
wherein at least one of the rotor (26) and the stator (28) comprises a multiple winding (30) with at least a first winding circuit (40-1) including first conductor segments (56-1) connected in series and a second winding circuit (40-2) including second conductor segments (56-2) connected in series, the first and second winding circuits (40-1, 40-2) being electrically isolated from each other and preferably from the ground (G),
the conductor segments (56-1, 56-2) comprising an inner conductor (58) and an outer electrical insulation (60),
wherein the first and second conductor segments (56-1, 56-2) are arranged such that conductor segments (56-1, 56-2) which have a direct contact with each other belong to different winding circuits (40-1, 40-2).
