in Southern France, Northern Italy, Switzerland and Southern Germany, this transmitter cannot be normally received well more than from Roumoules. However at night its transmissions may have at least the same range as those of the longwave system due to its skywave propagation. Power supply The Roumoules Transmitter consumes significant amounts of power, supplied by two transformers each capable of providing 5000 kW. The power is delivered to the transformers by a 150 kV and a 220 kV power line. The transmitter's power supply is larger than required (an equivalent supply would provide a community of 5000 with its own substation to the 150 kV grid supply). This redundant supply ensures reliable power for the transmitter. There is a backup generating set of on the site and a possibility to supply the station at reduced power from the local 20 kV grid.
