Answer Posted / mks
DG sets are always poised to start during an emergency, So
battery healthiness is important for the engine to start.
The healthiness of SMF (sealed maintenance free) batteries
cannot be ensured. If lead acid is used, by its Specific
gravity healthiness can be ensured during routine.

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
