No, it was between 784 and 805 W (230x3.4 or 230x3.5). The tension is 230 V in Italy.
This is called in Italy "eurotensione", google it. I already posted the link to
the italian wikipedia article abt mains tension in Italy. Must I repeat it? It was 220 V
there until the end of the 90ies. When I was a child, it was 110 V in some areas, I
remember it very well.
Lewan measured the tension in the Rossi showroom in april, and the tension was
even above 230 V: on 19th and 28th of april it was 236 V AC. I dont know why
Rossi talks about 220 V.
You are right that the current voltage (ref. *count Alessandro Giuseppe
Antonio Anastasio Volta*) is 230 Volt AC (50 Hz) in Europe; as a result
of European Harmonisation in 1995; but as you mention that was not
always the case.
In most European Continental countries (e.g. Belgium, Germany, France,
the Netherlands, Italy?, ...) , it used to be 220 Volt AC, but this was
gradually raised (during several years) in four steps from 220 Volt into
230 Volt (220 - 223 - 226 - 230), so industry could gradually make their
equipment (including lamps ("Glühbirnen") ) to work with the higher voltage.
The UK and Ireland were an exception and used to have 240 Volt AC, which
was lowered to the harmonised 230 Volt.
Although many people (including myself) know that nowadays the voltage
is 230 Volt, *_we often still say 220 Volt _*(while we actually mean 230
Volt), based upon Rossi's age (approx. 60 years) , I'm not surprised at
all that he talks about 220 Volt (while he actually means 230 Volt) as
that is the Voltage he used to have known for the greatest part of his live.
The fact that Rossi talks about 220 Volt only proves to me that he isn't
an electrical engineer, but he never claimed to be one either, but heck
that's not the business he is in, so I've no problem with it.
B.t.w. 110 Volt AC (60 Hz) is still used in the US and Japan.
As a side note: "tension" refers in my book and wikipedia's to :
"Tension (physics), a force related to the stretching of an object (the
opposite of compression)"
Kind regards,
