The program is utilized to perform a complete fault study of the distribution system of the VPI Electric Service, as an example test case. Equations are gathered and a computer program is written to calculate the fault current magnitudes on a distribution system when three phase, phase to phase, phase to phase to ground, or phase to ground faults occur. The program is written to include basic circuit types that are in use in the utility industry today. The program provides results that are in tabular form for easy use. The VPI Electric Service system is discussed and results are included for the major distribution circuits in the system. System maps have been prepared for the circuits and are available at the Electric Service. A user's guide is included so that the program can be used whenever system changes demand a new study.iv, 205 leavesBTDapplication/pdfIn CopyrightLD5655.V855 1977.H63Electric power distribution -- VirginiaThesishttp://scholar.lib.vt.edu/theses/available/etd-11092012-040259/
