FIELD: electricity.
SUBSTANCE: sounding electrical pulse is transmitted to the line; the signal reflected from the damaged point is received. The process of electrical pulses transmission and receipt is repeated, at that stating from the second pulse the pulses are transmitted at the moment of receipt of the pulses reflected from the damaged point in the line. The distance up to the damaged point is evaluated against repetition frequency of the received pulses.
EFFECT: improved accuracy.
