    • An insulated electrical component (10) of an insulated electrical machine includes a conducting element (12), a first radiographically-visible conductor sensor node (16) coupled to the conducting element (12), at least one second radiographically-visible conductor sensor node (16) coupled to the conducting element (12) a first distance in a predetermined direction from the first radiographically-visible conductor sensor node (16), and an insulating material (14) bonded to the conducting element (12). In some embodiments, the insulated electrical component (10) further includes a first radiographically-visible insulator sensor node (40) coupled to the insulating material (14) and not coupled to the conducting element (12) and at least one second radiographically-visible insulator sensor node (40) coupled to the insulating material (14) and not coupled to the conducting element (12) a second distance from the first radiographically-visible insulator sensor node (40). The radiographically-visible sensor nodes (16, 40) are distinguishable from the conducting element (12) and the insulating material (14) in a radiographic image. Methods of manufacturing and non-destructive testing of insulated electrical components (10) are also disclosed.
    • 绝缘电机的绝缘电气部件(10)包括导电元件(12),耦合到导电元件(12)的第一射线照相可见导体传感器节点(16),至少一个第二射线照相可见导体传感器节点 (16),其从所述第一射线照相可见导体传感器节点(16)沿预定方向与所述传导元件(12)连接第一距离,以及与所述传导元件(12)连接的绝缘材料(14)。 在一些实施例中,绝缘电气部件(10)还包括耦合到绝缘材料(14)并且不耦合到传导元件(12)的第一射线照相可见绝缘体传感器节点(40)以及至少一个第二射线照相可见 绝缘体传感器节点(40),所述绝缘体传感器节点(40)耦合到所述绝缘材料(14)并且不与所述传导元件(12)相距所述第一射线照相可见绝缘体传感器节点(40)的第二距离。 射线照相可见传感器节点(16,40)在射线照相图像中与传导元件(12)和绝缘材料(14)是可区分的。 还公开了绝缘电气元件(10)的制造和非破坏性测试的方法。
