Partial Discharge Diagnosis on GIS Based on Envelope Detection
In order to detect and identify the defects on GIS, the ultra-high frequency envelope detection circuit and high-speed data acquisition system was designed, and the tests of five typical defects for GIS were made in the laboratory and the envelope signal was acquired based on Ultra-high frequency (UHF) envelop detection circuit. And wavelet denoising technique was used to reduce the white noise...
متن کاملCharacteristic Analysis of Partial Discharge Detection in GIS
Abstract Partial discharge (PD) detection is a valuable method for the estimation of GIS condition, and the PD mapping is benefit for GIS defects identification. To investigate the PD characteristic of the GIS model, this paper simulates different PD maps of various fault simulations, and the characteristics of PD map is acquired by the pulse amplitude, phase and the discharge density to identi...
متن کاملResearch on Partial Discharge Localization in XLPE Cable Accessories Using Multi-Sensor Joint Detection Technology
A multi-sensor joint detection technology was proposed based on the theory of the high frequency current transformer (HFCT) method, Ultra-high frequency (UHF) method and acoustic emission (AE) method. An experimental partial discharge (PD) testing was applied on XLPE cable with artificial defect signals. The experimental results show that the multi-sensor joint detection technology will help to...
متن کاملResearch of Animal Disease Information System Based on GIS Technology
It is necessary to build animal disease information system in order to dynamically monitor and predict diseases distribution, and propagation, such as HPAI and FMD taking place, Powerful functions of data management analysis and display with the GIS can be applied oriented to animal disease information. This disease information platform can be applied to dynamiclly monitor and predict disease, ...
