Abstract
A method of measuring the density of a dielectric gas under pressure in a buried metal-clad electricity line consists in measuring the pressure and the temperature of the dielectric gas by means of a sensor mounted on the case of the line, and in compensating the pressure measurement as a function of the temperature measurement using constant density curves that have been corrected on the basis of a curve representing the difference between the temperature at the surface of the case of the line and the mean temperature of the gas inside the line for increasing amounts of current carried by the line conductor.
