Abstract: It is proposed a wound conductor arrangement for an electrical machine: the wound conductor includes ma wound conductor comprising an electrically conductive material having an electrical conductivity value, and an insulation layer being at least partially provided around the wound conductor by a shrinkable tube comprising insulating material. The wound conductor arrangement further includes an intermediate layer provided between the wound conductor and the insulation layer. The intermediate layer has a conductivity value less than the conductivity value of the wound conductor. Further, an electric machine is proposed including the wound conductor arrangement. A method is described for insulating a wound conductor for an electrical machine.

Abstract: The present disclosure provides a method for detecting an electrical discharge in an electrical apparatus. The method includes sensing an electromagnetic wave using an electrical sensor and generating an electric signal for a predetermined time period, sensing an acoustic wave using an acoustic sensor and generating an acoustic signal for the predetermined time period. The acoustic sensor is associated with at least one compartment of the electrical apparatus. Electrical data is generated based on a quasi-periodic characteristic of electric peak sequences of the electrical signal. Acoustic data is generated based on a quasi-periodic characteristic of acoustic peak sequences of the acoustic signal, wherein the electrical data is combined with the acoustic data to provide an operation status of the at least one compartment.
