Does anyone have any experience of testing when generators are involved? All ZS readings come out too high for RCBO's that protect the circuits! any help or advice would be greatly received.

to be honest i am not 100% sure on this. all i find is that when i am looking through my new companies test sheets that all zs readings are too high for RCBO's that are protecting the circuits. Are generators usually TNS earthing arrangement? Cables are run under the water so operating temperatures and everything are hard to determine. Company have the thought that if circuits are protected by RCBO's then they have done enough to which i would like clarification on.

In regards to an earth rod, ive just started working with generators especially tncs systems. I have found that an earth rod is used mainly as a lighting protector only and that any faults with the systems go to the star point on the transformer via the neutral. Meaning a rod is not always nessersary just like a ship as you said. Myself I would check all the earth connections and also the pen link at the genny. What is your ze at the genny? is that a normal reading
