Abstract
Abstract In this work, an attempt was made to study the spatial charge distribution in fibrous dielectrics using pulsed electro-acoustic method. The polarized dielectrics displayed in-depth charge polarization and exhibited slow charge decay. The initial charge density was found to increase with an increase in polarization voltage as well as polarization time. The statistical analysis revealed that though the polarization voltage affected the initial charge density significantly, the polarization time was insignificant. A multiple linear regression model of initial charge density was developed and found to predict the experimental results quite satisfactorily.
