Patent Number Title Of Patent Date Issued
8207743 Method for fault location in uncompensated power lines with two-end unsynchronized measurement June 26, 2012
A method is provided for fault location in uncompensated power lines with two-end unsynchronized measurement, finding an application in the power industry and for overhead and overhead-cable transmission or distribution lines. The method according to the invention includes measuring the
8183871 Method and device for fault location in a two-terminal transmission or distribution power line May 22, 2012
A method for locating a fault in a two-terminal power transmission or distribution line. Measurements of the three phase currents are received from both terminals. Measurements of the three phase voltages are received from one line terminal. Parameters of the line are received. The f
8131485 Method for fault location in electric power lines March 6, 2012
A method for locating faults in three-terminal and multi-terminal power lines, applicable in electric power systems for overhead and underground cable transmission and distribution lines. The inventive method is characterized in that it measures current for fault and pre-fault condit
7872478 Method and adaptive distance protection relay for power transmission lines January 18, 2011
A method and an adaptive distance protection relay for compensating for a remote line end infeed effect during determination of a distance to a resistive fault on a three-phase power transmission line. It is assumed that a fault current flows through the fault resistance. A fault loop
6924647 Fault location method and device August 2, 2005
The present invention relates to a method for calculating the distance to fault in a section of a power transmission network, which section is arranged with line terminals at both ends, each terminal including impedance relays (AA, BB), including the steps of, at the occurence of a f
6529010 Location of fault on series-compensated power transmission lines March 4, 2003
The present invention relates to a method for locating a fault on a power transmission line which is series-compensated with capacitors. The site of the fault is determined with the aid of measured currents and voltages at one of the two ends of the power transmission line before and aft
6483435 Method and device of fault location for distribution networks November 19, 2002
The present invention relates to a method for location of a fault which has occurred on one of a plurality of lines in a power distribution network where the location is performed with the measured values of the common supply voltage of the plurality of lines and the currents of the plur
