Abstract:
Space charge phenomenon in Low Density
Polyethylene (LDPE) is being investigated for more than two
decades. Several theories have been put forth by researchers.
Several experiments have been done and analysed on space
charge dynamics in general, yet, the understanding on
mechanism of space charge dynamics, field variations, charge
packet movement inside the material etc. is incomplete. In this
paper investigation has been done to observe the space charge
dynamics of LDPE/MgO, with different concentrations of MgO,
using Pulsed electroacoustic technique. Field enhancement due to
charge accumulation and distortion has been investigated for a
duration as long as five hours.
