Faulted Phase Decision Method Between Current And Voltage Based Delta Phase Selectors
US Patent:
2010005, Mar 4, 2010
Filed:
Oct 12, 2007
Appl. No.:
12/444428
Inventors:
Florin Peter Selejan - Wescosville PA, US
Assignee:
ABB TECHNOLOGY AG - Zurich
International Classification:
H02H 3/00
US Classification:
361 80
Abstract:
A method of identifying fault conditions in a three phase power system includes monitoring the changes of both the current and voltage properties on a three phase power network. A maximum phase change value of both the current and voltage is determined. Either the voltage or the current values are selected, whichever includes the largest maximum phase change. Thereafter, the selected set of measurements is analyzed to determine whether a fault condition exists on any phase of the three phase power.
