“…It's been reported that the most influential parameters for WT growth are the frequency, electric field strength and concentration of impurities [1,15]. It has been demonstrated that up to at least 30 kHz WT growth is proportional to the applied frequency, although for cables subjected to load cycling during ageing this may not hold [16].…”

This paper describes a pragmatic method to assess the resistance of medium voltage polymeric cable insulation to water treeing. Water trees (WT) with a length between 100 and 800 μm are produced in 12 days in the polyethylene insulation of commercial cable samples by use of a high frequency, high voltage power supply.The initial objective was to provide a source of information for asset management eg estimating the remaining life of installed cables. However, the very short time necessary to generate water trees with this method will allow its use for the assessment of new products and provides a rapid comparison technique between different materials. The obtained results show that WTs grow in all kinds of cables but depending on the insulation type, the shape and speed of growth are different.

“…It has been reported that the initiation and propagation of a water tree greatly differ for different electrolyte solutions [8] [9]. However, in the new water electrode, the initiation and propagation characteristics of a water tree generated by ionic species are unclear.…”

In this paper, we describe an investigation of the effects of ions and waveforms on water tree initiation and propagation utilizing a new water electrode method. The results indicate that ferric ions contribute to water tree initiation and propagation. Moreover, a water tree was initiated when the waveform of a pulse simulating an inverter waveform was applied for 2 weeks even at room temperature, in spite of no ac voltage application.
