Noise Spectroscopy and Diagnostics of High Temperature Insulating Materials
Original language description
The samples of insulation materials for operation at temperatures to 350 oC were tested in a high electric field. Tested materials covered with metal electrodes on both sides represent a parallel plate capacitor. The VA characteristics are proportional to Un where n  1. Partial discharges have an impact on conductivity at a high electric field and they are important sources of noise and acoustic emission signals. This phenomenon is related to the sample homogeneity and may be used for technologyy assessment and quality testing. The electromagnetic signal precedes the acoustic emission response and the time delay corresponds to the difference of propagation velocities of sound and electromagnetic radiation in the sample.
