The majority of the known methodses use the connecting resistance as criterion for purpose of the repair to insulation. The adapted design procedure of the data in which the stationary potential of steel in a ground can be is offered is determined in laboratory conditions, and calculation of force of polarizing current is carried out under condition of equality of force of the current moving in the opposite sides from a point of a drainage. The technique allows to estimate a condition of a covering without realization of route measurements, using only the data of periodic or intensive electromeasurements.
