  • Analysis of the D. C. electric field for a pipeline in a three layered earth

    Creator:
    Brandenstein, Albert Edward
    Abstract:
    This paper develops an equation, from an heuristic set of assumptions, which describes the axial current, leakage current, resultant electric field, and resultant earth potential occurring when a pipeline buried within a resistive earth is subjected to a distributed, primary, axial, electrostatic field produced from a high-voltage, direct-current (HVDC) power...

  • Frequency-domain, parameter estimation for a brushless, doubly-fed machine

    Creator:
    Ramchandran, Ashok
    Abstract:
    A Brushless, Doubly Fed Machine (BDFM) attempts to combine the advantages of conventional induction and synchronous types of electrical machines by its unique architecture. The validation of BDFM designs in an actual test environment requires the estimation of the BDFM model parameters from actual experimentation. Accurate values for the parameters...

  • A study of the effect of the rotor coil couplings of a synchronous machine on its predicted transient response

    Creator:
    Nehrir, Mohammad Hashem
    Abstract:
    The effect of the mutual inductances between the rotor coils of a synchronous machine on its defined reactances and predicted transients are investigated. Two linearized models of the machine are considered. One uses the Laplace-Transform approach, with minimum number of assumptions on the inter-coil couplings, in developing a model for...

  • A signal-processed antenna system and the simulation of the effects of balanced-mixer frequency conversion

    Creator:
    Spencer, Kenneth Edward
    Abstract:
    In this paper a signal-processed antenna and receiver system is proposed and analyzed. In addition, a simulation of the balanced-mixer portion of the processing system is made on a hybrid computer to find the bandwidth limitations for the total system. The system utilizes both the amplitude and phase information of...

  • Gas ratio and pressure effects on the 6328 A⁰ transition of the helium-neon gas laser

    Creator:
    Freytag, Edwin Karl
    Abstract:
    This is a review paper of current literature in the area of pressure effects on gaseous lasers. This thesis discusses the mechanisms which relate the relative power output of the 6328 A[superscript ⁰] neon transition to total and partial pressure variations of the helium-neon gaseous laser. The operation of the...

  • Analysis of brushless doubly-fed, stand-alone generator systems

    Creator:
    Gorti, Bhanuprasad V.
    Abstract:
    This thesis introduces a Brushless Doubly-Fed Machine (BDFM), stand-alone generator system. Development of a BDFM current-forced model, along with the analysis of air gap power distribution between the two stator windings and the rotor circuit, pave the way for the characterization and analysis of stand-alone generator systems. The main disadvantage...

  • Analysis and synthesis of exponentially tapered, nonuniform transmission line impedance transformers

    Creator:
    David, Frank Kolar
    Abstract:
    The exponentially tapered, nonuniform transmission' line, applied as an impedance transformer, is analyzed and modified. The analysis develops an expression for the input reflection coefficient that has the magnitude and phase as distinct functions. This allows ease in comparing the approximate and exact solutions and in developing the S-parameters for...

  • Instrumentation system for high speed data sampling of electrical machinery

    Creator:
    Brisbine, Glen Edward
    Abstract:
    The objective of this thesis is to develop criteria for a data acquisition system for electrical machinery capable of sampling a signal every 0.2 msec with a desired accuracy of 0.1%. The system to be measured includes both AC and DC voltage and current signals from several points. The main...

  • Microstrips on gold-doped silicon substrates

    Creator:
    Lai, Cheng-wen
    Abstract:
    The power dissipation of microstrip transmission-line on gold-doped silicon substrates was investigated. The gold-doping was applied to a regular n-type silicon substrate with resistivity of 5 to 10 ohm-cm. Insertion-loss tests were employed to measure the power dissipation of the microstrips. Power dissipation somewhat less than that for intrinsic silicon...

  • Identification of synchronous machine parameters

    Creator:
    Shaban, Ali Omar
    Abstract:
    The synchronous machine is an essential component of a power system and determination of its parameters accurately is an important task in securing adequate modes of operation through certain control strategies. An estimation technique based on the Powell algorithm was evaluated for the identification of these parameters on the basis...
