It depends on the technicians choice of voltage. You shoulb
able to get a guess of how much voltage the cable should
be able to0 endure without losing its insulation and then
subject that c abkle to that voltage on the megger. For
low voltage installations about 500V should be okay since
the maximum voltage of a three phase system will be 415V
if bridged.

Why efficiency in thermal power plant is low?
What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
