Charging of PE and XLPE specimens: effect of antioxidant and cross-linking on luminescence features, space charge and conduction current measurements

We have performed a series of electrical and optical measurements with the aim of improving the understanding of the mechanisms of transport and trapping of charges on three materials that constitute steps for manufacturing of cross-linked polyethylene, that is, low-density polyethylene, cross-linked polyethylene in the absence of antioxidant and conventional cross-linked polyethylene.
