Influence of solid and liquid antioxidants on the formation of space charge in the XLPE insulation of medium voltage cables

Influence of solid and liquid antioxidants on the formation of space charge in the XLPE insulation of medium voltage cables

In this work, the influence of antioxidants in solid and liquid states was studied on the formation of space charge when cross-linked polyethylene (XLPE) was insulated in medium voltage cables that were thermally treated for up to 168 hours at a temperature of 120 °C. The results, which used the pulsed electro-acoustic technique (PEA) with a voltage of 120 kV applied to the cable show the use of solid antioxidants in an increased formation of bulk charge in the XLPE in comparison to those who have used liquid antioxidant. The PEA measures are consistent with those obtained by the thermally stimulated depolarization currents (TSDC) technique, which also have a greater depolarizing current in samples that use a solid antioxidant.
