Abstract :
To improve the manufacturing of multi- composites of solid insulation materials, this paper has studied the space charge distribution in pure, micro- and nano-filled composites of solid dielectric materials at various high impulse voltages. The pulsed electro-acoustic (PEA) method has been used as one of the most effective techniques for the measurement of the space charge distribution in insulating materials. This can measure the space charge profiles every 10 musec so, the effect of stressing on impulse breakdown voltage has been investigated. Results of PEA measurements performed on various kinds of multi-dielectrics are presented and discussed.
