Diapositive 1 sur 0... Once a temperature of 1 500 °C has been reached, the molten material is poured into a casting ladle.

Temperatures during the period were above normal and 0 8 °C higher than in the first quarter 2015, which led to a 3.8TWh decrease in the volume of electricity sold to end customers. Sales benefited from the regulated tariff increase in France on 1 August 2015 (+ 140 million) .

These measurements were carried out on an which allows heating the core of large cross-section cables up to 90 °C . Thanks to a stabilized 50 Hz power supply and a device for cancelling the reactive component of the signal, EDF Power Networks Lab technical teams determined the AC resistance of the conductor with an accuracy of 0 15 % and then deduced the impact of the skin effect.
