The aging test mainly refers to the thermal oxygen aging test of rubber, plastic products, electrical insulation materials and other materials; or the ventilation aging test for electronic parts and plastic products. Seven aging test methods: At present, there are many aging test methods for polymer materials, ...
To improve the reliability and quality of electric power systems, preventive diagnosis and regular maintenance of high voltage capacitors are required. Dielectric response measurements in both time domain and frequency domain are potential tools for assessing the condition of dielectric of high voltage capacitors. Modern measurements in time domain include ...
Criteria for qualitative assessment of sensors include determination of effective measurement frequency, susceptibility to variations in salinity, dielectric relaxation and temperature and a look at spatial variation in sensor sampling area. ...
In order to estimate qv, EM systems make use of the dependence of soil dielectric 9 permittivity on qv. However, a standard method for characterizing and comparing EM system 10 measurement capability has not been established. Our objective was to evaluate the permittivity 11 measurement ability of seven different EM sensing systems using readily available media. 12 Sensing system ...
