Mine cable partial discharge denoising method based on multivariate variational mode decomposition and improved wavelet threshold

The insulation state of the mine cable plays an important role in the stable operation of the mine power supply system. Partial discharge on-line monitoring is an important means of cable insulation state monitoring. Aiming at the problems that the mine cable partial discharge signal is easily subme...
