Distribution of a dielectric gaseous mixture to a high-voltage apparatus

A method of distributing an electrically insulating liquefied gas mixture to high-voltage electrical equipment from a storage means containing an electrically insulating liquefied gas mixture, the method comprising the following steps:

• Step a):
• heating the electrically insulating liquefied gas mixture to a temperature such that the contents of the storage means are a homogeneous fluid;
• Step b):
• withdrawing the electrically insulating liquefied gas mixture resulting from step a) to fill high-voltage electrical equipment by raising the temperature of the electrically insulating liquefied gas mixture resulting from step a);
• wherein, during step b), a set value for regulation is applied at variable pressure, calculated in real time based on weighing the storage means, when the change in the set value of pressure is less than 0.2 bar per 1 kg/m3 of change in density, and then a set value for regulation is applied at constant temperature until the storage means is emptied of its content.
