Abstract: A system and method of automatically detecting electrical discharges in a gas insulated switchgear equipment and locating the electrical discharges in real-time is disclosed. The method includes sensing an ultra high frequency (UHF) signal generated from the electrical discharges at multiple channels simultaneously. The UHF signal sensed at multiple channels are reviewed simultaneously to determine whether they are of the same electrical discharge or not. The method also provides the sensed UHF signal at multiple channels to an artificial intelligence training model trained to determine the type of electrical discharge such as a partial discharge or an arc. The method provides a location of the electrical discharge based on an attenuation profile associated with the multiple channels and other information including amplitude information and distance information between adjacent channels.

Abstract: Provided are flexible interconnect circuits comprising signal circuit elements. For example, a signal circuit element can be formed from the same metal sheet as a signal trace, thereby being monolithic with the signal circuit element. This integration of signal circuit elements into a flexible interconnect circuit reduces the number of additional operations and components (e.g., attaching external circuit elements). In some examples, a flexible interconnect circuit is used in a battery pack for interconnecting batteries while providing external terminals on the same side of the pack. Specifically, a flexible interconnect circuit comprises an interconnecting conductive layer (for connecting to batteries) and a return conductive layer, both extending between the first and second circuit edges. Each of these conductive layers comprises a corresponding external terminal at the first edge, while these layers are interconnected at the second edge.
