METHOD FOR DETERMINATION OF SHORT CIRCUIT SPOT ON OVERHEAD POWER TRANSMISSION LINE AGAINST MEASUREMENTS AT TWO ENDS THEREOF

摘要

FIELD: electricity.SUBSTANCE: method for damage detection includes determination of the line parameters against measurements made at two ends at the moment of short-circuiting, determination of the relative distance up to the short circuit spot with further specification of the distance up to the short circuit spot. Technical result lies in usage of measured phase current and voltage values and full phase and phase-to-phase values of the line resistance.EFFECT: increased accuracy of damage spot detection.3 cl, 3 dwg
