Hi,
Just had a bit of a heated discussion with a friend of mine about electricity meters and I decided to get some info from you chaps so I can promptly add some ammo to my argument next time we meet!
The claim is that you will get a low resistance reading between phase and neutral meter tails coming out of a property's electricity meter before it reaches the distribution board when the power is off. Apparently the phase and neutral are linked together in the electricity meter through a coil.
Personally I just don't agree. How could this be possible? Wouldn't it cause a dead short?
Or,
..is it true that the meter works on a kind of separated circuit prinicple like a transformer but with the exception being that the phase on one coil is linked to the other so to provide the Earth loop to the substation which is needed during a fault scenario for quick supply disconnection
