No!! You will have to disconnect the connection which is
usually bolted to the earth electrode.

Then with earth megger you will have to test the earth
electrode independently.

Answer / zan

It should be checked accordingly the resistance used for
the solid system earthing.
In low voltage system erathing, the secondry winding of
distribution transformer, low voltage generator or UPS
system are normally solidly earthed. Solidly earthing of
the system means that the system voltage will never exceed
the phase voltage.

Answer / anil

now days simple measuring instrument are availsble eg:-
meco i have seen catloge by which without connecting to
Eatrh Electrode we can measure leackage current as well as
resistance of Earth point/Electrod.

Assuming that a dedicated neutral earthing transformer is provided for each GT generator, when the two generators are running in parallel, has consideration been given that the earth fault current from one generator stator winding be split between the two neutral earthing transformers? If so, what adverse impact will this have on the operation of the 59N and 27TN devices?
