What earthing arrangement is this and will RCDs operate

vantech

Hi, 

I found the below image on an IET forum. 

electrical.theiet.org/.../

The voltage potential between L&N (well, line and line) is 230V, with the voltage between each of these lines and the CPC sitting at 115V. 

The article states this is a TN-S earthing arrangement if a reference to earth is made using a rod, however I note there is no N-E relay/bond. 

Can anyone confirm this is correct and that this is indeed a TN-S earthing arrangement? 

Will RCDs connected to the output of the supply operate correctly, I presume so because current can flow between line(s) and CPC. 

Thanks.

    The Victron inverter with the earth link parked on the dummy terminal is simply “unearthed” from how I am looking at it.
