20140111219 | METHOD FOR LOCATING SHORT CIRCUIT IN AN OVERHEAD POWER TRANSMISSION LINE BY UNSYNCHRONIZED MEASUREMENTS AT BOTH ENDS THEREOF - The claimed invention relates to the power industry and can be used for locating short circuits in power transmission lines by measuring the instantaneous current and voltage values when unsynchronized measurements are taken at both ends of the line. It is a technological object of the invention to improve the accuracy of damage location. The technical result of the invention is achieved by accurately synchronizing the current and voltage values measured at the ends of the line and unsynchronized in time on measurement. Synchronization is effected by aligning the oscillograms at both ends of the line with the short circuit start section. | 04-24-2014 |
