摘要

A method suitable for evaluating the state of thermal solicitation of an electric cable for energy transmission, comprising the steps of measuring the current that effectively passes in the conductor of the cable and at at least one point the temperature of the external surface of the cable same, to transform the preceding measures respectively into a first and a second electrical signal to them proportional, characterized in that it also comprises the following successive phases of introducing: said second electrical signal in a circuit capable of outputting a third signal electrical proportional to the maximum admissible current in the cable conductor for the temperature of the external surface considered: said first and contemporarily said third electrical signal in an instrument apt to instantaneously measure the relationship between the values of the two signals supplied to it.
