Abstract
A device for detecting the length of a drilling column that has a plurality of pipes (1) assembled on couplings (2) is characterized in that on the pipes (1), there is at least one electrical line (3, 4) that is galvanically connected to the couplings (2). On one end of the electrical line (3, 4), there is a means (7) for the feed of electrical pulses into the electrical line (3, 4) and for detecting the propagation time of the electrical pulses from the means (7) to a reflection site on the other end (5) of the electrical line (3, 4) and back.
