An artificial neural network for pollution evaluation is introduced in this paper which contributes to design an expert system for flashover predicting. The network measures four parameters (peak impulse current, maximum low-frequency current, humidity and voltage) which reflect the insulating property of an insulator and outputs the pollution level. After enough of training, the outputs of the network...
Degradation of electrical characteristics of NdAlO3/SiO2 stack gate under the constant voltage stress (CVS) is presented. It is found that the electron trapping, positive charges and oxide trap generation acts together, which causes the degradation of NdAlO3/SiO2 stack gate. The transport mechanisms of the gate leakage current in NdAlO3/SiO2 stack gate are also investigated. Frenkel-Poole emission...
I-V characteristic of the HfO2/SiO2 stack gate MIS capacitor is investigated. The gate leakage current in HfO2/SiO2 stack gate MIS capacitor decreases after constant voltage stress, which is caused by electron trapping. By analyzing the experiment and calculation results, the main transport mechanisms of the gate leakage current in HfO2/SiO2 stack gate is presented. The different transport mechanisms...
In this paper, leakage current flowing along contaminated ceramic insulators was separated into low frequency component and pulse component, which were detected respectively by Rogowski coil in artificial contamination tests. The effects of the operating voltage, the equivalent salt deposit density and humidity on the two characteristic components of leakage current were investigated. It is revealed...
