why the under of transformer platform is filled with rock stones.
Answer Posted / rajeshsan
There are many reasons for using gravel stones of 60mm size below transformer. Few are:-
1. During oil spillage from transformer or during sprinkler system act the water draining from soak pit it will be easier.
2. To avoid the grown of grass and entry of animals etc.,
3. To reduce the step potential
You can please refer the NFPA 850 for details.
