Step down transformers used in residential AC Mains distribution

[Brian82784]

TL;DR

When the voltage rises on the primary what happens to the secondary?

Hello,

If we have a pole top mounted distribution step down transformer for residential use what happens to the voltage on the secondary side if the primary side voltage increase?

Thank you

It increases proportionally.

It increases proportionally.

I guess it depends on how much that primary side voltage increases...
