Answer / william lobo

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.

why 3phase is 440v but where as we get phase voltage 220v,we have to get 220*3=660v.can u pleas give in detailed
