Abstract:
In three single phase high voltage underground cable induce voltages and currents in their sheaths. The sheath induced currents are undesirable and generate power losses and reduce the cable ampacity whereas the induced voltages can generate electric shocks to the workers that keep the power line. This means that when dealing with three single phase high voltage underground cable, it is very important to know the sheath currents called circulating currents that can circulate throughout the sheath and sheath voltage of the cables. It is very useful to know their values and the technique to reduce the sheath voltage of the high voltage Cable. This study presents as technique known as Mixed bonding technique combination of cross bonding and single point bonding to reduce the sheath voltage of the long length cable route.

Abstract:
Three-phase underground power cables can induce voltages and currents in their recover sheaths. The induced voltages and currents in sheath are undesirable. They generate heat losses and reduce the cable ampacity. Moreover, the induced voltages can generate electric shock to the workers, who maintain the power cables. It is very important to predict the sheath voltages and currents, which depend on different parameters, such as the sheath grounding system, the geometry of the cables, the gap between them, etc. In this paper, the voltages and currents induced in sheath for different installation of underground power cables (trefoil and flat formation) are studied and presented. For each case study of installation, the results of sheath voltages and currents have been computed and compared. Finally, the case of cross bonding with increasing of cable spans can reduce the sheath voltage significantly.

Abstract:
The number of high-voltage parallel cables is rapidly increasing. The alternating magnetic field generated by the working current of power cable cores induces voltage in the adjacent metal sheath; if the sheath and earth form a circuit, the metal sheath will create a circulating current, resulting in a reduction in the load capacity of power cable and the life of cable insulation. This paper uses MATLAB to construct a model for calculating the circulating current of cables connected in parallel in the same phase, and the effects of cable arrangement, phase sequence, and loop distance of cables connected in parallel on the sheath circulating current are investigated. The induced voltage in power cable sheaths is decomposed into two components, i.e., the component resulting from the core current and the component resulting from the metal sheath. Two new sheath connection methods are proposed to suppress the sheath circulating current. Compared with traditional cross-connection grounding, the proposed methods can reduce the coupling degree between loops, thus decreasing the induced voltage and circulating current. The different grounding methods of the sheath are modeled in the environment of an electromagnetic transient program (EMTP), and the sheath circulating current is simulated and compared with the conventional cross-connection grounding method. In the asymmetric arrangement, the proposed series connection method can reduce the sheath circulating current by at least 50%; however, its increases the sheath circulating current in the symmetric arrangement.

Abstract:
The current and voltage in High Voltage DC (HVDC) line is not pure DC but contain superimposed ripple components. The current ripple in core of HVDC cable magnetically induces a voltage in the sheath, whereas the voltage ripple causes the flow of charging current from core to sheath. The knowledge of sheath voltage is necessary to ensure compliance with the specification of utility companies. In this work, we have reported that the models available in commercial Electromagnetic Transient (EMT) simulation software erroneously introduce a DC bias in steady-state sheath voltage and sheath current. We have also demonstrated that by removing the DC bias accurate steady-state evaluation of sheath voltage and sheath current is possible. Additionally, we have analyzed the sheath voltage and currents in HVDC cable considering different cable lengths and sheath grounding schemes. It has been found that grounding the sheath at the terminal of HVDC cable can limit the sheath voltage to acceptable levels without causing substantial joule loss in the sheath.

Abstract:
Abnormal heating of composite insulators of high-voltage transmission lines concentrate at its end, especially in a high-humidity environment. In order to study the influence of end-sheath aging and moisture absorption on abnormal heating of composite insulators, in this paper, we first discuss the appearance test, temperature rise test, and dielectric characteristic test conducted on 110 kV decommissioned composite insulators. Test results indicated the temperature rise in composite insulators increased with ambient humidity, but temperature rise was not severely affected by surface contamination of its shed and sheath; in dry environments, the dielectric constant and dielectric loss factor of high-voltage end sheaths are higher than of those of medium- and low-voltage end sheaths, and the loss effect becomes more severe after moisture absorption in a high-humidity environment. After the tests, the authors established a COMSOL simulation model of composite insulators, to analyze changes in the electric field and thermal field of the end sheath of composite insulators due to the coupling of electric and thermal fields. It was concluded that the dielectric constant of a high-voltage end sheath of the composite insulator increased after moisture absorption, distorting the partial electric field on the surface; meanwhile, the dielectric loss factor increased significantly after water molecules intruded into the aging layer of the sheath as polar molecules. Therefore, the dielectric loss (leakage conductance loss and lossy polarization loss) caused by aging and moisture absorption of the sheath surface under partially high field strength in the high-humidity environment was the leading cause of abnormal heating at the high-voltage end of composite insulators. The conclusion of this paper serves as an important reference for revealing the causes of abnormal heating of composite insulators in high-humidity environments and the influence mechanism of external factors on abnormal heating.

Abstract:
High-voltage direct-current composite insulators are faced with various challenges during operation, such as creeping discharge, umbrella skirt damage, abnormal heating and insulator breakage. Among them, the aging of the interface between the core rod and the sheath is one of the important causes of composite insulator failure. In order to improve the electrical resistance of the composite insulator interface, this study uses plasma etching to modify the surface of the glass-fiber-reinforced epoxy resin plastic to prepare the high-voltage direct-current composite insulator core rod–sheath samples. By analyzing the surface morphology of the epoxy resin, static contact angle and surface charge transfer characteristics, the control mechanism of the plasma etching treatment on the interface bonding performance and leakage current of composite insulator core rod–sheath samples were studied. The results show that proper etching time treatment can improve the trap energy level distribution and microstructure of epoxy resin and increase the discharge voltage along the surface; chemical bonding plasma etching can improve the interfacial bonding performance of core rod–sheath samples sheaths, reduce the leakage current of composite insulator core rod–sheath samples sheath specimens and improve their interfacial performance.

Finally, the application and technical effect of the smooth aluminum sheath are analyzed, which provides a reference for the production and practical engineering application of the smooth aluminum sheath technology.

Abstract:
The physics of interactions between waves in plasmas and sheaths for background magnetic fields which make oblique angles with sheath surfaces is studied with the use of the self-consistent finite element code rfSOL incorporating the recently developed sheath impedance model [J. R. Myra, Phys. Plasmas <strong>24</strong>, 072507 (2017)]. The calculation based on this model employs the generalized sheath boundary condition (sheath BC), which surpasses the previously used capacitive sheath BC in reliability by taking into account the contributions of the ion and electron currents in the sheath and the displacement current. A series of numerical simulations is carried out in two-dimensional slab geometry with a flat or curved sheath surface as part of the boundary. It is shown that the sheath&ndash;plasma wave appears when the equilibrium magnetic field line angle with respect to the sheath surface is small, the absolute value of the radio-frequency (RF) sheath voltage is large, and the plasma density is slightly higher than the lower hybrid resonance density (LHR density), all of which bring the sheath property closer to being capacitive. It is also shown that the sharp variation of the magnetic field line angle along the sheath surface can sensitively affect the maximum absolute value of the RF sheath voltage at a plasma density slightly lower than the LHR density.

Abstract:
We have numerically studied the bifurcation properties of a sheet pinch with impenetrable stress-free boundaries. An incompressible, electrically conducting fluid with spatially and temporally uniform kinematic viscosity and magnetic diffusivity is confined between planes at x1=0 and 1. Periodic boundary conditions are assumed in the x2 and x3 directions and the magnetofluid is driven by an electric field in the x3 direction, prescribed on the boundary planes. There is a stationary basic state with the fluid at rest and a uniform current J=(0,0,J3). Surprisingly, this basic state proves to be stable and apparently to be the only time-asymptotic state, no matter how strong the applied electric field and irrespective of the other control parameters of the system, namely, the magnetic Prandtl number, the spatial periods L2 and L3 in the x2 and x3 directions, and the mean values B¯2 and B¯3 of the magnetic-field components in these directions.

Abstract:
碩士<br>國立彰化師範大學<br>電機工程學系<br>98<br>Generally speaking, the single-core power cables with metallic shield layers are used in medium high voltage underground power cables. The metallic shield layers of power cables can not only provide shielding effect but also serve as a fault current route to transmission line systems duration malfunction. The induced voltage caused by the effect of electromagnetic current in power cable shall meet the requirements of safety rules. Its potential strength is closely correlated with conductor-loaded current, interval between two manholes, and arrangement of power cables. To prevent high voltage from endangering human beings and to eliminate circulation loss in the cycle electric current, the induced voltage in single-conductor cable sheaths shall be limited to the lowest possible safety value and shall be designed with an appropriate sheath-bonding method. In this thesis, Electro Magnetic Transients Program (EMTP) and Matrix Laboratory (MATLAB) are used to study the relationships between the settings of power cable arrangement and induced voltage. It is hoped that the findings in this paper can serve as a reference to the construction of underground power cable lines in the future. The goals to save construction costs, to reduce the manhole covers, to decrease the fault rates, and to increase the quality of power system can be achieved.

Yoon, to design the planar-type coil of the planar-type ICP(inductively coupled plasma) system. And we successfully set a planar-type ICP system. We observe that during the E-H transition, plasma potential has apparent change,just like Sang-Hun Seo's observation. Generally speaking,ion current density exponentially decrease with the height. We measure the plasma sheath propagation under -2kV voltage pulse and the current on the electrode. The current includes displacement current, ion current, electron current, and secondary electron emission. We often want to subtract the displacement current and the secondary electron emission current. If we measure the displacement current without plasma and subtract it from the current measured when plasma was on, there will be inaccuracy. It's because the pulse waveform were different in two conditions. We can use the equation I=C*dV/dt to compute the correct displacement current,where C is the capacitance between the electrode and the vacuum chamber. To compare the ion current density dritribution and the sheath propagation velocity, the result is reasonable.

Abstract:
Any discussion of the pathomechanisms and treatments of MS benefits from an understanding of the physiology of the neuronal membrane and the action potential. Neurons and glia, are important for signal propagation, synaptic function, and neural development. The neuronal cell membrane, maintains different ionic environments inside and outside the cell, separating charge across the membrane and facilitating electrical excitability. Ion channels allow flow of sodium, potassium, and calcium ions across the membrane at selected times. At rest, potassium ion efflux across the membrane establishes the nerve membrane resting potential. When activated by a voltage change to threshold, sodium influx generates an action potential, or a sudden alteration in membrane potentials, that can be conducted along an axon. The myelin sheaths around an axon, increase the speed of conduction and conserve energy. The pathology of MS disrupts the myelin structures, disturbs conduction, and leads to neurodegeneration. Ion channels have been the target of investigation for both restoration of conduction and neuroprotection.

AbstractElectromagnetic forming is a kind of high-speed forming technology for improving the formability of aluminum alloy sheets; however, the inherent non-uniform electromagnetic forces always restrict its application into the micro-forming field. Electromagnetic-impacted micro-forming processes were adopted by using flexible mediums for force transmission. The processes of electromagnetic-impacted rubber micro-forming, electromagnetic-impacted micro-hydroforming, and electromagnetic-impacted pneumatic micro-forming were compared to inspect the influences of flexible mediums. The effects of discharge voltages on the electromagnetic-impacted micro-forming processes of an AA5052-O aluminum alloy thin sheet were investigated by the numerical simulation of electromagnetic and mechanical coupled fields. The numerical simulations were validated via comparisons with the experimental results; these showed that the forming accuracy and thickness uniformity of micro-channels were the greatest by the electromagnetic-impacted micro-hydroforming process.

Abstract:
With the development of cities, the application of high-voltage cables in cities is becoming more and more extensive. The induced voltage generated during the operation of the cable will affect the normal operation of the cable line, and when the cable sheath takes grounding measures, it will form a loop with the earth, and at this time, a current will be formed in the sheath, which will make the cable temperature rise, and in serious cases, it will lead to cable failure and affect the stability of the power system. Based on the ATP-EMPT platform, this paper carries out the simulation analysis of two grounding modes of single-end grounding and medium-indirect grounding of parallel laying cable lines. The simulation results show that when the resistance of the ground resistance is approximately equal to the equivalent resistance of the cable sheath, the circulation current can be effectively suppressed. The recommended laying length of the two laying methods is not more than 6km for single-end grounding and 12km for intermediate direct grounding.

Abstract:
Micron particle sorting has an important role in biomedicine, renewable energy, and micro-manufacturing. In this study, a fishbone-shaped micron particle sorting device was designed based on the dielectrophoretic manipulation of micron particles technique. Firstly, the simulation model of multi-physics field coupling is established using experimental data, and the results are calculated and analyzed using the method of finite element analysis. Finally, according to the simulation results, the factors affecting particle manipulation are particle dimensions, number of electrodes, voltage magnitude, and sheath flow rate. Studies have shown that when the sorting particle diameter is different, increasing the sheath flow speed, voltage strength, and the number of electrodes can improve the sorting effect. By modifying the factors affecting the dielectrophoretic manipulation of micron particle sorting, it can make the present design applicable to the sorting of different micron-size particles and provide a significant reference value for the subsequent particle sorting method.
