Abstract :
The present paper reports the preliminary results of an investigation of the dielectric properties in the frequency range of ~10 -5 to 104 Hz, growth of water tree density and the spatial behavior of polarization in LDPE films aged in 0.1M NaCl solution for a time period ⩽454 hours with an AC field of 6 kV/mm at 1 kHz at room temperature and at 65 °C by the laser intensity modulation method (LIMM)
