Fault Voiceprint Signal Diagnosis Method of Power Transformer Based on Mixup Data Enhancement
A voiceprint signal as a non-contact test medium has a broad application prospect in power-transformer operation condition monitoring. Due to the high imbalance in the number of fault samples, when training the classification model, the classifier is prone to bias to the fault category with a large...
