in a Tn-c-s system when as in circuit measurement does the earth and neutral become seperate ie line to neutral not line to earth neutral. as the neutral and earth are combined at the consumer input.

I'm an electronics engineer not an electrician but...

The neutral wire has resistance/impedance so moving any distance away from the point where earth and neutral are combined _may_ effect the measurements you make... but it will depend on what measurement you are making.
