Szukana fraza: [Abstrakt = "The work presents a conception of electrochemical cathodic protection of a pipeline by means of voltage travelling waves generated by a source of repetitive voltage pulses. A single voltage pulse moves in the form of a voltage travelling wave that reaching pipeline end reflects backward without changing its polarity. The reflected part of the voltage wave superposes with the incoming one, strengthening, at the same time, polarization of the pipeline end. The above conception was verified by polarization of a steel pipeline at first with constant voltage and then with repetitive voltage pulses. Hence, pipeline polarization with repetitive voltage pulses enables increasing of the length of pipeline section that might be subject to effective electrochemical protection supplied from a single source."]
