A combined model based on improved information entropy and vague support vector machine (IVSVM) is introduced into transformer fault diagnosis using dissolved gas analysis in oil (DGA). The method used to obtain the weights of each weight raw data, processed training data corresponding types are inputted (VSVM) classifiers. Firstly, weighted by discretise original from mixed state for subsequent classifier training. Then, set divides events true, false unknown factors, which can optimise...
This study presents a combined model based on the exploratory factor analysis (EFA) and least square support vector machine (LSSVM) to predict contamination degree of insulator surface. Firstly, EFA method is utilised reduce numerous influence variables into few variables, which could decrease complexity model. Then, regarding above as new input LSSVM established degree. In order obtain optimal predictive value, non-dominated sorting genetic algorithm II applied optimization parameters. The...
Composite insulators, which use high temperature vulcanized (HTV) silicone rubber as shed material, are widely applied in transmission lines. Ice accumulation on their surfaces may inflict flashover accident and even massive power outage. In this study, a superhydrophobic (SH) coating HTV was fabricated by the sol–gel process combined with plasma jet treatment method. It found that as-prepared SH exhibited prominent superhydrophobicity an excellent self-cleaning property water contact angle...
Abstract Bis(tetrabutylammonium)bis(2‐thioxo‐1,3‐dithiole‐4,5‐dithiolato)mercurate(II) was prepared and characterized by elemental analyses, electronic absorption, infrared X‐ray powder diffraction spectroscopy. The specific heat of the crystal measured to be 1878.2 J.mol –1 K at 300 K. thermal decomposition process investigated means thermogravimetric analysis differential measurements in air together with spectra. third‐order nonlinear optical properties 800 nm were femtosecond Kerr gate...
The interleaving technique is required for LLC resonant converters to achieve high power level and handle higher input/output current. However, conventional pulse-frequency modulated (PFM) face challenges of load current sharing due component tolerances tanks. In this paper, a hybrid rectifier employed in interleaved compensate the voltage gain each module sharing. By adopting an active switch diode rectifier, provides additional voltage-regulation ability, thus good current-sharing...

Abstract Based on the relationship between electrical equipment discharge and ultraviolet radiation, this paper proposed use of UV pulse method to detect switchgear arcing faults. Switchgear protection system based new technique detects faults by analyzing produced electric arc. This was implemented tested in laboratory, performance module verified: it is capable calculating number pulses quickly precisely, which indicates intensity fault arc, therefore can be applied for detecting

Under the EIT-based light-storage regime, transverse spatial carried probe field stored into coherence. By manipulating frequency and propagation direction read control field, transferred...
In this work, we experimentally demonstrate an image information transfer between two channels by using slow light based on electromagnetically induced transparency (EIT) in a solid. The probe optical is slowed due to steep dispersion EIT. By applying additional control field EIT-driven medium, the transferred into channels. Image intensities can be controlled adjusting of fields. similarity output images further analyzed. This allows for manipulating fashion, and will important processing.
We experimentally report on the preservation of transverse spatial coherence in storage double light pulses by using a solid. Under electromagnetically induced transparency, two probe are stored into atomic between ground-state levels and later retrieved. By analyzing Young-type interference patterns formed fields before after storage, we demonstrate that is preserved process. This demonstration can be used for image processing multiple information manipulation.
