Space charge measurement using the acoustic technique has become a common method for investigating dielectric properties of solid materials. Among various techniques, the Pulsed ElectroAcoustic (PEA) method has been used for various industrial applications, such as for the evaluation of high voltage insulation. Typical PEA systems can measure space charge profiles in the thickness direction of specimens. “PEANUTS system for 85C Test Chamber” is available to be used under such a high temperature/environment. The amplifier part of PEANUTS is set out of test chamber to avoid getting damage cause of high temperature as 85℃.
Feature 1) Non-destructive 2) High capability for the electrical noise avoidance. Since it can avoid electrical noise, measurement under high voltage application is possible. 3) Automatic repetitive measurement is available by software. 4) Reproducibility is excellent. 5) Easy operation, handling. It is only putting the sample between the two electrodes.
