Zero-Sequence Impedance Of A Three-Phase Transmission Line With Ground Return , Marion Edwin Forsman

#### Zero-Sequence Impedance Of A Three-Phase Transmission Line With Ground Return , Marion Edwin Forsman

*Retrospective Theses and Dissertations*

The equation for the zero-sequence impedance of a three-phase transmission line with ground return and the equation for the electric intensity in the earth were derived following the method of Carson. The equation for the impedance was identical with the equations of Carson, however, the electric intensity equation derived included more terms than the equation of Carson. The additional terms were due to the two additional conductors in the three-phase line;A solution of the equation for the electric intensity could not be found and numerical solutions for three particular transmission line configurations were made. The results of these calculations ...

#### An Analogue Computer For Network Analyzer Stability Studies , Charles Melville Davis

*Retrospective Theses and Dissertations*

An electro-mechanical analogue computer has been described which simulates in conjunction with the 10-kc power amplifiers in the Network Analyzer the rotor inertia and the governor of a synchronous generator. The computer eliminates the need of tedious, time-consuming, step-by-step calculations in a transient stability problem and makes possible a more accurate analysis;The computer requires further development in order to maximize its capabilities and broaden the scope of inquiry possible with it. The application of the computer to non-linear problems outside the power system field is desirable and should be investigated.
