1. Técnica do Pulso Eletroacústico para medidas de Perfis de Carga Espacial em Dielétricos / Electro-acoustic Pulse to Measure Space Charge Profile in Dielectric Materials
It is described the implementation of the electroacustic pulse technique, PEA, for the determination of space charge profiles in dielectrics. The method is based on the acoustic signal generated by the application of a voltage pulse with short duration on the sample. The acoustic signal generated by pulse is detected by using a piezoelectric transducer coupl
