The article describes how a robust classification system can be set up and evaluated using the example of typical partial discharges in gas-insulated DC systems.
Partial discharges (PD) in large electric machines are a critical phenomenon often misunderstood. Partial discharges are neither harmless nor extremely dangerous. They indicate a localized electrical breakdown within the insulation of high-voltage equipment. Over time, especially in the long term, PD can deteriorate th...
The approaches to the rational selection of equipment for electromechanical complexes of oil and gas production enterprises and the optimization of its operating mode to achieve maximum oil recovery are considered
This study designs a multi-parameter detection platform to investigate inter-turn discharge faults in transformer oil-paper insulation. Experiments on typical defect modelreveal distinct differences in breakdown characteristics and PRPD spectra. Statistical feature analysis shows that the EMA change rate of ultra-high...
The article discusses the types of electric braking of electric train, provides a comparative analysis of mechanical braking systems, and provides an example of the effectiveness of regenerative braking at the Omsk electric train depot.
