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.

Abstract: A multi-phase busbar for conducting electric energy includes: a base layer of an insulating material; a first conducting layer of a sheet metal; a first insulating layer of an insulating material arranged on the first conducting layer; a second conducting layer of a sheet metal arranged on the insulating layer; and a second layer of an electrically insulating material which is arranged on the second conducting layer. The first and/or second insulating layers include spacers, each spacer including a layer of a rigid insulating material. At least one of the spacers is glued to an electrically insulating coating of the first and/or second conducting layer, and/or at least one of the spacers is glued to an electrically conductive surface of an uncoated first and/or second conducting layer by an adhesive.
