<p>The method involves establishing voltage difference between outlet terminals of sub-stations (20A, 20B), so that the current (I) circulates on a continuous current electric supply line (10) between the sub-stations. The continuous current electric supply line is de-iced between the sub-stations by the heat produced by the circulation of the current, and a voltage measuring device is provided at an outlet of one of the sub-stations. The voltage difference is chosen and controlled between the outlet terminals of the sub-stations.</p> |
