Paper Abstract

The importance of the present study is that the dielectric characteristic of powder materials with high specific resistivity can affect the electrostatic precipitator operation, electrostatic daub, lightning strikes, etc. This paper studied and analyzed a test system for the dielectric characteristics of high-resistivity powder, including current leakage and breakdown voltage. The resistivity range of the system was from104Ω•cm to 1014Ω•cm. The test voltage was from 0.5kV to 30kV (direct current), and the least leak current was 10-9A. The test temperature was from room temperature to 300°C. The system is capable of testing and studying the resistivity and the high-voltage field intensity of electrical breakdown of industrial powders under various laboratory conditions. Results show that this system has applied widely in China and it has obtained the invent patent in China.
