@RODALCO2007 Is there a formula for those distances?
-
i don't think i know about this type of cooling, (ON/OB) mostly familiar with ONAN and ODAF... and did anyone catch the vector type? they didn't show enough of the Rating and Diagram plate
-
@ryan29073 because its 3 phase that means 3x50hz audioble waveforms. wouldn't it be a 150hz sinewave instead, or am i confused
-
@RODALCO2007 ha, thats like in australia, it was officially 240, but changed to 230 +5 -10% I think, to match the UK. the voltage seems to nominally be 240 though anyway.
-
@RODALCO2007 The UK voltage didn't actually change from 240v to 230v. They just changed the spec. to 230v +10% -6%! Us crazy Brits eh!
-
Cool, Love the Hum it makes.
-
@c0rrupts3ct0r555 what if he works there? :)

In France, approximately since 1985, we use 230V (and 50Hz of course), like most european countries.

So remind me again how someone can be standing in the middle of the substation, grounded (on the ground) but not have arcs flying everywhere to them and them getting electrocuted? I've never understood that.

@tall32guy As long you maintain your minimum approach distance ( MAD ) for the voltage in use.
For example 33kV 60 cm, 110kV 1.5 meters.
This applies to trained and qualified service personnel.
For the public it is over 4 meters.

Due to the whole X square calculus thing, the noise you here is actually 100 hz not 50. that's probably why the difference between 50 and 60 hz seems so great.
ryan29073 1 year ago
@ryan29073 You are wrong there. 50 or 60 Hertz power or audio is a full cycle e.g. a positive and negative part of the sine wave.
Same as with audio frequencies in the higher ranges.
You confuse it with ripple through a full wave bridge rectifier, The 50Hz ripple becomes 100Hz for the filter circuit.

Does Europe use 240vac or 220 in their homes?
ryan29073 1 year ago
@ryan29073 It used to be 220 Volts but was increased to 230 Volts in the 90's to standardize the European voltages.
In many parts of Eastern Europe, France and Italy the voltage is still 220 Volts as far as I'm aware.
