  • Internal impedance of conductors of rectangular cross section
    IEEE Transactions on Microwave Theory and Techniques, 1999
    Co-Authors: Giulio Antonini, Antonio Orlandi, Clayton R. Paul
    Abstract:

    It is shown that the resistance and internal Inductive Reactance of a conductor of rectangular cross section are not equal when skin effect is well developed, i.e., when the cross-sectional dimensions are much larger than a skin depth, unlike the case of a conductor of circular cylindrical cross section. Hence, the high-frequency internal inductance cannot be determined from the resistance and must be computed separately. Also, the widely used time-domain representation of the internal impedance B/spl radic/s is not valid. Numerical results are given for conductors of various cross-sectional aspect ratios and dimensions.

  • Internal impedance of conductors of rectangular cross section
    1998 IEEE EMC Symposium. International Symposium on Electromagnetic Compatibility. Symposium Record (Cat. No.98CH36253), 2026
    Co-Authors: Giulio Antonini, Antonio Orlandi, Clayton R. Paul
    Abstract:

    It is shown that the high-frequency (skin effect) internal resistance and internal Inductive Reactance are not equal for conductors of rectangular cross section as they are for conductors of circular cross section such as wires. A numerical method is used to demonstrate this and to show the errors incurred in using this approach.

  • Studi Perbaikan Faktor Daya Beban Induktif dengan Kompensator Reaktif Seri Menggunakan Sakelar Pemulih Energi Magnetik
    Tidar University Magelang, 2012
    Co-Authors: Fauzan F.
    Abstract:

    Today, most of the load of electrical power system is Inductive that has low power factor so that the necessary equipment that can compensate the Inductive Reactance produced by the load. One of the equipment that can be used to compensate the Inductive Reactance is “SAKELAR PEMULIH ENERGI MAGNETIK” / MERS (Magnetic Energy Recovery Switch)which work to regulate the set time of charging and discharging of capacitor by controlling the ignition angle shift of moset gate on the connecting structure of magnetit energy recovery switch. MERS is installed between the voltage source and a single phase induction motor as the load so that it can set the supply voltage to the load. MERS which is used to repair the power factor and it can affect the terminal voltage on the induction motor that can affect the changes in rotation speed of induction motor. Reactance value capacitor will be high when capacitance value of the capasitor is low, Reactance value of MERS will be small when the angle shift of mosfet gate bigger. When the Reactance valve of MERS the voltage waveform in the capacitor is not-continuous, when Reactance value of MERS is equal with Reactance value of capacitor its waveform is balance, reacatance value of capacitor is smaller than Reactance value of MERS its voltage waveform is dc-offset. The result of study showed that MERS can repair the power factor to 0,999 and it affects the changes in the terminal voltage of Inductive load so tha it effect on the speed of rotation of single phrase induction motor.

  • Transport Properties of Lithium Ions Doped Vanado-Bismuth-Tellurite Glasses
    'AIP Publishing', 2016
    Co-Authors: Keshavamurthy K., Eraiah B.
    Abstract:

    The glasses of composition (65-x)V2O5-xLi2O-20TeO2-15Bi2O3 (x = 15 and 25 mol%) were prepared by conventional melt quenching method and their electrical conductivity and dielectric measurements have been carried out in the frequency range 40Hz to 6MHz over a temperature 373 to 473 K. The conductivity values increased with both Li2O concentration and temperature. Interestingly, the dielectric response showed the existence of a negative capacitance effect in the present glass system and concluded that this effect arose from the presence of external Inductive Reactance

  • STUDI PERBAIKAN FAKTOR DAYA BEBAN INDUKTIF DENGAN KOMPENSATOR REAKTIF SERI MENGGUNAKAN SAKELAR PEMULIH ENERGI MAGNETIK
    [Yogyakarta] : Universitas Gadjah Mada, 2012
    Co-Authors: Dr. Eng. Danang Wijaya, S.t. F. M.t,.
    Abstract:

    Nowdays, most of electric loads character in industry is Inductive which definetly has low power factor and caused Inductive Reactance raises. This Inductive Reactance need to be compansated using apropriate equipments. One of them is the Magnetic Energy Recovery Switch (MERS) which to set capacitor charging and discharging time by controlling firing angle shift of mosfet gate in MERS circuit. MERS is installed between voltage source and single phase induction motor as the load so it controls voltage to the load. As an equipment that gives correction to power factor, MERS also effect terminal voltage on induction motor that lead to changes in rotation speed of motor. Capacitor Reactance is high when capacitance is low, and MERS Reactance is small when firing angle of mosfet gate is big. When the capacitor Reactance is bigger than MERS Reactance then capacitor voltage has discontinue waveform, when they are equal then its waveform is balance, and when capacitor Reactance is smaller than MERS Reactance then its waveform is dc-offset. This study results that MERS is able to correct power factor up to 0.898 with load voltage 244.6 volts using C = 2.2 µF at firing angle of 1600 and lead to changes of voltage terminal of Inductive load
