Hello all,
@Camomac, you got it right in the calculation. However, it holds good only for a 1-Ph system as the input. For a 3-Ph system, dont forget to add "Root 3" to the formula.

Hello all,
If the system is 3-Ph 4 Wire (i.e. Star connected, neutral grounded transformer), the voltage on any phase to ground will rise only in case one of the other two phases develops a low impedance earth leakage due to insulation failure.
In this case, there seems to be one. However, if...
