Voltage between Neutral and Earth

[Sb8389]

Hi guys,
came across a fault yesterday on a job where I was getting 15v between neutral and Earth at two sockets on a ring main.if u need anymore details let me know.
i am unsure what would cause this and want your expert opinion as I have never come across this problem.

the installation is an old 3036 board no RCD
TNS system

your replies are appreciated

it could be a phantom voltage. try with an analogue meter. if it's still there, check all earthing and bonding and the cpc connections on the socket circuit.

What was the voltage between neutral and earth, measured at the terminals in the board?

Did you turn off the other circuits?

it sounds like induction to me
