    ABSTRACT: Interfacial tension (IFT) and acid numbers of insulating oil are correlated with the number of years that a transformer has been in service and are used as a signal for transformer oil reclamation. Oil sampling for IFT measurement calls for extra precautions due to its high sensitivity to various oil parameters and environmental conditions. The current used technique to measure IFT of transformer oil is relatively expensive, requires an expert to conduct the test and it takes long time since the extraction of oil sample, sending it to external laboratory and getting the results back. This paper introduces a new technique to estimate the IFT of transformer oil using ultraviolet-to-visible (UV-Vis) spectroscopy. UV-Vis spectral response of transformer oil can be measured instantly with relatively cheap equipment, does not need an expert person to conduct the test and has the potential to be implemented online. Results show that there is a good correlation between oil spectral response and its IFT value. Artificial neural network (ANN) approach is proposed to model this correlation.

    ABSTRACT: The paper aims to reveal the relation between the inverse piezoelectricity of singlestranded DNA (ssDNA) film and the origin and sign of the deflection of microcantilever produced by the DNA immobilization. By using Zhang???s two-variable method for strain field of laminated beam and the linearized Poisson-Boltzmann equation for bioelectric potential of polyelectrolyte brush, an approximate model is presented to confirm the previous conjecture that the sign of the piezoelectric constant of ssDNA film might decide the sign of the surface stress. There is only one fitting parameter (piezoelectric stress constant) needed in the simplified model, which greatly reduces the difficulty of identifying the nanoscale electrical/mechanical properties of DNA film. Numerical fitting curves based-on the analytical models agree well with the pertinent experimental dada. The difference between the previous four-layered model and the present two-layered approximate model is also compared.

    ABSTRACT: This paper presents a comparative study on SF6 alternative candidate gases for the surface insulation performance of eco-friendly Gas Insulated Switchers (GIS) and Solid Insulated Switchers (SIS). The candidate gases including N2/O2 mixture gas, dry air, and compressed air were proposed based on AC surface flashover experiment. These gases were compared and examined based on their surface insulation performance, pressure and gap dependence, surface insulation reliability in different temperatures, economic feasibility and easiness of manufacture. The comparison results verified that dry air had excellent properties on the comparison criteria and was the most suitable eco gas among the candidate gases for eco-friendly GIS and SIS. In addition to the comparative study on the candidate gases, their surface flashover characteristics were described in detail based on the effect of moisture contained in the candidate gases on flashover voltage and the correlation among electric field intensity, collision-ionization coefficient, electron attachment coefficient, and gap length.

    ABSTRACT: We developed a new wearable wristband-type piezo-sensor for detecting the pressure signals from the heartbeat. A piezoelectric porous electret made from electro-spun poly(tetrafluoroethylene) (PTFE) was used as the piezo-sensor material. This lightweight and flexibile porous PTFE electret exhibited high and stable piezoelectricity, enabling the realization of a piezo-sensor in a new wearable wristband-type instrument. Using the instrument, we observed a signal with detection accuracy equal to that of an electrocardiogram.

    ABSTRACT: A novel method for long-range detection and potential location of arcing faults on electrical distribution networks is described and investigated. When a network fault induces an electrical arc it is accompanied by the radiation of electromagnetic transients that can be detected remotely as a radio frequency signal. By capturing its wavefront at more than one monitoring location the time-difference-of-arrival between monitoring station pairs can be used to establish the origin. This approach is used to locate lightning arcs where the emissions are referred to as sferics. A key advantage of detecting faults by capturing the radiometric emissions from their arcs is that no direct connection is required to the plant being monitored, eliminating the need to take it out of service for either installation or maintenance of the radiometric monitoring equipment. This approach also has the potential for wide area coverage as opposed to monitoring a single specific circuit. In this paper, we describe the development and trialing of a monitoring network comprising 4 geographically separate receiving stations with an inter-station distance of less than 20 km. The utilization of GPS steered time-stamps overcame the fundamental challenge of providing a common, accurate, synchronized time-stamp for the transient signals received at each station. As well as providing the basis for fault location, this information allowed signals to be correlated with the network fault records. The system was proven to capture emissions from fault-induced arcs, but none of the captures were made at more than a single monitoring station, hence the efficacy of the system at locating fault-induced arcs could not be evaluated. However, lightning strikes were captured simultaneously at several monitoring stations and successfully located; demonstrating that the data capture methodology does allow signal origins to be determined. Further study is needed regarding the propagation distances of fault induce- radiometric emissions, particularly their rate of attenuation with distance.

    ABSTRACT: Antiferroelectric films of Sn doped Lead Lanthanum Zirconate-Titanate [(Pb, La)(Sn, Zr, Ti)O3, Sn-PLZT] with nano-grains were fabricated by aerosol-deposition (AD). The AD process produced highly dense films without visible pores. The polarization-electric field hysteresis loop and the phase transition behavior of PLZT with Sn doping into the B-sites were characterized. The grain sizes of the AD Sn-PLZT films, which were on the nano-scale, were controlled by the annealing temperature. Regardless of the compositions, the films with the nano-grains by the AD process showed less hysteretic behavior and larger stored energy. The Pb0.97La0.02(Zr0.85Sn0.13Ti0.02)O3 (PL-0.13) film deposited by AD and annealed at 750 °C for 1 h showed an energy storage capacity and efficiency of 13.0 J/cm3 and 78.9 %, respectively.

    ABSTRACT: In this paper, we report a disposable microfluidic impedance cytometer attached on a reusable printed circuit board (PCB) with dielectric layer for single cell detection. The cover slide acts as a dielectric layer which allows the AC signal to sense the impedance change cross the microfluidic channel. The microfluidic chip can be disposed; while the bottom PCB with pre-deposited electrodes is reusable after each sample test. We experimentally demonstrate that the developed device is able to selectively detect HeLa cells, a type of umor cells, and ignore Red Blood Cells (RBCs). Integration of low cost and disposable microfluidic chip with reusable PCBs widely available in the industry is of great potential in point of care diagnosis of cancer, especially in the developing countries.

    ABSTRACT: This paper presents the fracture failure mechanism of composite insulators that have been deployed for only one year on 750 kV transmission lines in strong wind areas. Investigations indicate that the flexible shed structure was vulnerable to flow-induced oscillation, which further brought cracking to the shed root. The interactive process of fatigue and fracture was reviewed by inspecting the failed samples to gain insight into the cracking mechanism. The fatigue theory of silicone rubber was introduced to illustrate the fatigue resistance of the material. Simulations of wind load and stress distribution were performed to demonstrate the load condition and stress concentration at the root area on sheds. Wind tunnel tests show the oscillation of two types of 750 kV insulators under strong winds of up to 60 m/s. Four samples of silicone rubber from major insulator manufacturers were tested to investigate the fatigue resistance property, and withstand limit of high- and lowperformance silicone rubbers. Results indicate that, composite insulators without specific design and wind tunnel tests were risky to apply on transmission lines in strong wind areas, which is common type of climate in northwestern China.

    ABSTRACT: This experimental study reported electrical properties of linear low density polyethylene (LLDPE)/MgO nanocomposites, which were prepared by melt blending methods. The effects of surface modified MgO nanoparticles on the microstructure, space charge distribution, thermally stimulated current and DC breakdown strength of the nanocomposites were investigated. The addition of surface modified nanoparticles increases the amount of spherulites and decreases their sizes. It is found that the LDPE/MgO interface shows significant influence on electrical properties of nanocomposites. The addition of MgO nanoparticles is available to suppress the production of space charges and enhance the DC breakdown strength, depending on the loading levels of nanoparticles. Thermally stimulated currents of nanocomposites reveal strong correlation between the traps and electrical properties of nanocomposites. It is believed that this study would provide important hint to design and develop advanced polymer nanocomposites for dielectric applications, in particular the HVDC applications.

    ABSTRACT: The secure operation of Gas Insulated Switchgear (GIS) is crucial for the bulk power systems, since the failure of GIS apparatus would cause severe interruption of power transforming and power supply at substations. Therefore, the monitoring and maintenance schemes of GIS devices have gradually taken the reliability-based indices into account, of which Partial Discharge (PD) levels in online monitoring are of substantial significance because PD serves as a major cause of insulation break-down. Ultra High Frequency (UHF) method is becoming widely adopted as the major inspection approach for PD in GIS. This paper presents the experiment-based results of the frequency characteristics of UHF signals caused by PD in typical defects using entire GIS operating system platforms. Specifically, the results covered the propagation attenuation of the UHF signals with peak to peak value and cumulative energy through typical structures, including basin-type insulators, L-shaped branch, isolating switches, current transformers, etc. The results serve as substantial criteria for optimal band width selection for high frequency detection, and as notable concerns to improve the sensitivity of UHF detection and the efficiency of online monitoring by effectively locating the external sensors for PD UHF detection.

    ABSTRACT: LDPE nanodielectrics show good space charge suppression performances, reducing the electric field distortions and improving the electric strengths. The decrease of space charge accumulation of LDPE nanodielectrics with increasing the nanoparticle loadings can be explained by the reduction of charge injection, the enhancement of conduction, and so on. However, the phenomena that the conductivities of LDPE nanodielectrics decrease firstly and then may increase with increasing the nanoparticle loadings has not been fully understood. A bipolar charge transport model consisting of charge injection, charge migration, and charge trapping, detrapping, recombination dynamics is used to investigate the space charge accumulation and conduction properties of LDPE nanodielectrics. Based on simulation results and existing experimental results, we discuss the influencing factors for space charge accumulation and conduction properties of LDPE nanodielectrics. It is found that the heightening of injection barrier plays a more important role in the suppression of space charges and the reduction of conductivities of LDPE nanodielectrics. Whereas, the variation of trap density and trap energy will regulate the nanoparticle loading dependent conduction properties.

    ABSTRACT: This paper addresses classifying different common partial discharge (PD) types under different acoustic emission (AE) measurement conditions. Four types of PDs are considered for the multi-class classification problem, namely; PD from a sharp point to ground plane, surface discharge, PD from a void in the insulation, and PD from semi parallel planes. The collected AE signals are processed using pattern classification techniques to identify their corresponding PD types. The measurement conditions include the influences of various PD locations, oil temperatures, and having a barrier in the line-of-sight between the PD source and the AE sensor. A recognition rate of 94% is achieved when classifying the different PD types measured at the same conditions. In addition, it has been found that the different PD source locations, oil temperatures, and barrier insertion have an impact on the recognition rate. However, by including AE samples at these different conditions in the training process, a recognition rate around 90% for all cases is achieved.

    ABSTRACT: In this study, we developed an amorphous indium-gallium-zinc oxide (α-IGZO) thinfilm transistor (TFT) incorporating high-κ Sm2TiO5 gate dielectrics. The high-κ Sm2TiO5 α-IGZO TFT after annealing at 400 °C exhibited very good electrical characteristics, such as a high Ion/off ratio of 5.27--107, a high field-effect mobility of 27.8 cm2/V-sec, a low threshold voltage of 0.2 V, and a low subthreshold swing of 136 mV/decade. These results are probably due to the incorporation of Ti into the Sm2O3 film, resulting in the formation of good Sm2TiO5 gate dielectric and low density of interface states at the oxide/channel interface.

    ABSTRACT: This paper presents a novel mixing formula for computing the effective complex permittivity of layered dielectrics and composites in the microwave frequency range. The newly derived formula for the slab-shaped mixed dielectrics and composites is substantially different from other mixing equations present in the literature, as the proposed formula computes the effective permittivity in terms of the weighted volume ratio and the dielectric properties of the constituent materials. The weighted volume ratio takes into account the effect of the electric field configuration of microwave field interacting with the material under test. The applicability of the proposed mixing model is tested using both the simulated and the measured data for a number of cases. The effective complex permittivity of all the equivalent mixed dielectric samples computed using the proposed mixing formula matches quite well with the corresponding data measured in the microwave frequency range. Finally, the relative percentage error between the measured effective permittivity and its computed value using the proposed mixing formula is calculated in order to quantify the results.
