Propagation characteristics of water trees using full and half-cycle rectified voltage waveforms

In this paper, we describe the propagation characteristics of water trees in cross-linked polyethylene (XLPE) using full and half-cycle rectified voltage waveforms. The results show that water trees under the application of a positive full-cycle rectified voltage propagate considerably further than those under other waveforms, regardless of the voltage frequency and application time. Moreover, water trees under a negative half-cycle rectified voltage propagate more than those under a sinusoidal voltage.
