AC voltage

    Hi,
    I was tinkering with my new digital multimeter and I came across
    this problem with the ac voltage supply of my house. The potential
    difference between the live wire and the neutral wire is 271V (multi
    set to V~). This I assume is the Vm in the equation of Vmsin(theta).
    Next the potential between Live and earth wire was 221V and funnily
    the potential between earth wire and neutral wire was 28V. Now how can
    the earth wire be at a potential higher than the neutral wire? What
    could be the problem?
    Thanks,

    Perhaps there is a poor gound, along with ground currents.
     
  3. Multimeter reads rms value whereas Vm is peak value of voltage.

    I don't know what the electrical code for india says, but should earth
    and ground not be connected together?
