Revealed yellow alarms 'accelerated'
the cause is the increased flow of energy
To repair a fault, the island was separated from the continental network, using its own, but the change has caused problems in the 'balance' of power

From the Corriere della Sera | The mystery of the clocks in Sicily: all along
CATANIA - You have unlocked the mystery of the clocks 'speed up' of eastern Sicily. Neither funny nor appropriate, let alone paranormal phenomenon: rather it would be the consequence of a temporary increase in the flow of electricity. Clock radios that go on for five minutes a day and a microwave oven with timer problems: these are some of the abnormalities seen in Sicily for about three weeks, exactly on time served to the company that manages the distribution of electricity to complete the maintenance ordinary sole undersea cable linking Sicily to Calabria.
For about twenty days the island was separated from the 'continental network "and was self-sufficient in the supply of electricity. But Sicily, energy, produces more than it consumes, and this has created some problems in the "balance" of power delivered to users has fluctuated between 50 and 50.13 Hertz (Hz), creating small "acceleration" to the timer household appliances. In levels strictly according to law, since the rule is a variation between 49 and 50 Hz, which is the number of oscillations performed by the electric current in a second alternate.
The phenomenon has already been used up by the conclusion of the routine maintenance of submarine cable to the one existing in fact "detach" the power grid from the European circuit in Sicily. So the island's network is powered by the hydroelectric system, which is more stable, but also from alternative sources, whose production is not constant. This can create very small changes in frequency, the "dilution" with the continental system makes minors. "The phenomenon is not new - the professor explains Rosario Lanzafame, professor of machinery and power systems at the University of Catania - but it has been noticed and has had more widespread because of the social network and private TV stations that have magnified the incident , giving rise to network in the "yellow watch" in Sicily, but is not mystery. It was a network problem isolation but has been resolved. It will happen again the next departure from the continental network, but it is nothing serious. "
