METHOD OF DETERMINING SPATIAL DISTRIBUTION OF ELECTRIC CHARGE IN SOLID DIELECTRIC MATERIALS

摘要

Usage: The invention relates to a technique of measurement of the electric charge in the dielectric materials and can be used in the electrical and electronic industry, as well as in scientific research and industrial laboratories for nondestructive testing of internal electrostatic charges in dielectrics. SUMMARY OF THE INVENTION: The aim of the invention is to increase the measuring accuracy of the spatial distribution of charge in solid dielectrics. This aim is achieved in that the method of measuring the distribution of space charge in solid dielectrics provided comprising in the excitation of the acoustic signal in the test sample pulse laser light and recording and Ku hundred induced electric signal taken from the electrodes of the charged sample, and characterizing the distribution of the space charge, further irradiated with an electrically neutral sample identical test, record the electrical signal taken from its electrodes, and nvertiruyut its relatively akustoindu--skilled electrical signal m is produced by the summation signal, and the resultant electric signal is judged on the spatial distribution of charge. 1 yl. ff with
