Grid substation get the huge rate of power from different power sources like wind, thermal, hydro etc. and all the power points assembled at a mid point is called Grid.
Basically it is located at the power generation side like Outdoor substation.

Substation : it will distribute the power from the Local areas like using step down transformers. Normally this type of substations will be located at the distribution side like indoor substations

Answer / jithendra

sub station & grid sub station

SUB STATION : geting power from source means 132 to 6.6 KV

GRID SUB STATION : geting power from the turbine or thermal
Haveing multi circuit

last week we did the REF relay test by closing single pole (R phase) of CB and apply 380V at the primary of delta transformer. we get 33A at the primary of the R phase star end. but we get 380A at both R an B in delta side. how and why?
