Abstract: Provided are a transformer winding and a method for constructing a transformer winding. The transformer winding includes: a winding conductor having a ring structure; a first insulating layer wrapped on a surface of the winding conductor formed by winding; a conductor tape attached in an unclosed surrounding manner to a surface of the first insulating layer along a circumferential direction of the first insulating layer, where the conductor tape is attached to a position having a minimum value of a leakage flux on the surface of the first insulating layer; a first shielding layer attached to the surface of the first insulating layer with the conductor tape attached thereto; a second insulating layer cast outside the first shielding layer; and a second shielding layer wrapped on an outer surface of the second insulating layer.

Abstract: A method includes interpreting a contactor open event and a contactor load value for a contactor positioned on a motive power circuit for a mobile application, determining that a contactor opening event under load has occurred in response to the contactor open event and the contactor load value, and updating a contactor wear condition in response to the contactor opening event under load, wherein updating the contactor wear condition comprises accumulating a number of the contactor opening events under load.
