TRANSFORMER CLEARANCE FROM VAULT ROOM WALLS

TRANSFORMER CLEARANCE FROM VAULT ROOM WALLS

TRANSFORMER CLEARANCE FROM VAULT ROOM WALLS

(OP)
Hi!

Can anybody inform me of the required minimum clearance of a transformer (in this case, an oil immersed 1000kVA 13.8/0.415kV, indoor/outdoor type, ONAN) to the walls of the vault room? We will install this transformer and will construct a 4m x 3m vault room.

Thanks,
Arvin

RE: TRANSFORMER CLEARANCE FROM VAULT ROOM WALLS

I guess there are no exposed live parts in the transformer. In that case in ths part of world (India), we provide at least 750mm around the transformer for the purpose of ease of access. This  is as per the recommendation of one of authorities (TAC).

Good day gives you happiness, Bad days give you experience. Count Both....

that is correct skm, the bushings are enclosed inside a trafo box.

Would 500mm clearance suffice?

Thanks
Arvin
